+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+Welcome to the SeaBIOS project! This project implements an X86 legacy
+bios that is built with standard GNU tools.
+
+Please see build and developer information at:
+
+ http://seabios.org/Developer_Documentation
+
+For the impatient, SeaBIOS is built for QEMU and tested on QEMU with:
+
+ make
+ qemu -bios out/bios.bin
+
+SeaBIOS can be configured with kconfig. To change the default
+configuration one can run "make menuconfig" prior to running "make".
+
+For other types of builds, and for more detailed developer
+documentation, please see the online documentation listed above.

+The SeaBIOS code can be built using standard GNU tools. A recent Linux
+distribution should be able to build SeaBIOS using the standard
+compiler tools.
+
+Building SeaBIOS
+================
+
+First, [obtain the code](Download). SeaBIOS can be compiled for
+several different build targets. It is also possible to configure
+additional compile time options - run **make menuconfig** to do this.
+
+Build for QEMU (along with KVM, Xen, and Bochs)
+-----------------------------------------------
+
+To build for QEMU (and similar), one should be able to run "make" in
+the main directory. The resulting file "out/bios.bin" contains the
+processed bios image.
+
+One can use the resulting binary with QEMU by using QEMU's "-bios"
+option. For example:
+
+`qemu -bios out/bios.bin -fda myfdimage.img`
+
+One can also use the resulting binary with Bochs. For example:
+
+`bochs -q 'floppya: 1_44=myfdimage.img' 'romimage: file=out/bios.bin'`
+
+Build for coreboot
+------------------
+
+To build for coreboot please see the coreboot build instructions at:
+<http://www.coreboot.org/SeaBIOS>
+
+Build as a UEFI Compatibility Support Module (CSM)
+--------------------------------------------------
+
+To build as a CSM, first run kconfig (make menuconfig) and enable
+CONFIG_CSM. Then build SeaBIOS (make) - the resulting binary will be
+in "out/Csm16.bin".
+
+This binary may be used with the OMVF/EDK-II UEFI firmware. It will
+provide "legacy" BIOS services for booting non-EFI operating systems
+and will also allow OVMF to display on otherwise unsupported video
+hardware by using the traditional VGA BIOS. (Windows 2008r2 is known
+to use INT 10h BIOS calls even when booted via EFI, and the presence
+of a CSM makes this work as expected too.)
+
+Having built SeaBIOS with CONFIG_CSM, one should be able to drop the
+result (out/Csm16.bin) into an OVMF build tree at
+OvmfPkg/Csm/Csm16/Csm16.bin and then build OVMF with 'build -D
+CSM_ENABLE'. The SeaBIOS binary will be included as a discrete file
+within the 'Flash Volume' which is created, and there are tools which
+will extract it and allow it to be replaced.
+
+Overview of files in the repository
+===================================
+

+This page describes the process of obtaining diagnostic information
+from SeaBIOS and for reporting problems.
+
+Diagnostic information
+======================
+
+SeaBIOS has the ability to output diagnostic messages. This is
+implemented in the code via calls to the "dprintf()" C function.
+
+On QEMU these messages are written to a special debug port. One can
+view these messages by adding '-chardev stdio,id=seabios -device
+isa-debugcon,iobase=0x402,chardev=seabios' to the QEMU command line.
+Once this is done, one should see status messages on the console.
+
+On coreboot these messages are generally written to the "cbmem"
+console (CONFIG_DEBUG_COREBOOT). If SeaBIOS launches a Linux operating
+system, one can obtain the cbmem tool from the coreboot repository and
+run "cbmem -c" to view the SeaBIOS diagnostic messages.
+
+Additionally, if a serial port is available, one may compile SeaBIOS
+to send the diagnostic messages to the serial port. See the SeaBIOS
+CONFIG_DEBUG_SERIAL option.
+
+Trouble reporting
+=================
+
+If you are experiencing problems with SeaBIOS, it's useful to increase
+the debugging level. This is done by running "make menuconfig" and
+setting CONFIG_DEBUG_LEVEL to a higher value. A debug level of 8 will
+show a lot of diagnostic information without flooding the serial port
+(levels above 8 will frequently cause too much data).
+
+To report an issue, please collect the serial boot log with SeaBIOS
+set to a debug level of 8 and forward the full log along with a
+description of the problem to the SeaBIOS [mailing list](Mailinglist).
+
+Timing debug messages
+=====================
+
+The SeaBIOS repository has a tool (**scripts/readserial.py**) that can
+timestamp each diagnostic message produced. The timestamps can provide
+some additional information on how long internal processes take. It
+also provides a simple profiling mechanism.
+
+The tool can be used on coreboot builds that have diagnostic messages
+sent to a serial port. Make sure SeaBIOS is configured with
+CONFIG_DEBUG_SERIAL and run the following on the host receiving serial
+output:
+
+`/path/to/seabios/scripts/readserial.py /dev/ttyS0 115200`
+
+Update the above command with the appropriate serial device and baud
+rate.
+
+The tool can also timestamp the messages from the QEMU debug port. To
+use with QEMU run the following:
+
+`mkfifo qemudebugpipe`\
+`qemu -chardev pipe,path=qemudebugpipe,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios ...`
+
+and then in another session:
+
+`/path/to/seabios/scripts/readserial.py -nf qemudebugpipe`
+
+The mkfifo command only needs to be run once to create the pipe file.
+
+When readserial.py is running, it shows a timestamp with millisecond
+precision of the amount of time since the start of the log. If one
+presses the "enter" key in the readserial.py session it will add a
+blank line to the screen and also reset the time back to zero. The
+readserial.py program also keeps a log of all output in files that
+look like "seriallog-YYYYMMDD_HHMMSS.log".
+
+Debugging with gdb on QEMU
+==========================
+
+One can use gdb with QEMU to debug system images. To do this, add '-s
+-S' to the qemu command line. For example:
+
+`qemu -bios out/bios.bin -fda myfdimage.img -s -S`
+
+Then, in another session, run gdb with either out/rom16.o (to debug
+bios 16bit code) or out/rom.o (to debug bios 32bit code). For example:
+
+`gdb out/rom16.o`
+
+Once in gdb, use the command "target remote localhost:1234" to have
+gdb connect to QEMU. See the QEMU documentation for more information
+on using gdb and QEMU in this mode.
+
+When debugging 16bit code, also run the following commands in gdb:
+
+`set architecture i8086`\
+`add-symbol-file out/rom16.o 0xf0000`
+
+The second command loads the 16bit symbols a second time at an offset
+of 0xf0000, which helps gdb set and catch breakpoints correctly.
+
+To debug a VGA BIOS image, run "gdb out/vgarom.o" add use the gdb
+command "add-symbol-file out/vgarom.o 0xc0000" to load the 16bit VGA
+BIOS symbols twice.
+
+If debugging the 32bit SeaBIOS initialization code with gdb, note that
+SeaBIOS does self relocation by default. This relocation will alter
+the location of initialization code symbols. Disable
+CONFIG_RELOCATE_INIT to prevent SeaBIOS from doing this.

+This page provides a high-level description of some of the major code
+phases that SeaBIOS transitions through and general information on
+overall code flow.
+
+SeaBIOS code phases
+===================
+
+The SeaBIOS code goes through a few distinct code phases during its
+execution lifecycle. Understanding these code phases can help when
+reading and enhancing the code.
+
+POST phase
+----------
+
+The Power On Self Test (POST) phase is the initialization phase of the
+BIOS. This phase is entered when SeaBIOS first starts execution. The
+goal of the phase is to initialize internal state, initialize external
+interfaces, detect and setup hardware, and to then start the boot
+phase.
+
+On emulators, this phase starts when the CPU starts execution in 16bit
+mode at 0xFFFF0000:FFF0. The emulators map the SeaBIOS binary to this
+address, and SeaBIOS arranges for romlayout.S:reset_vector() to be
+present there. This code calls romlayout.S:entry_post() which then
+calls post.c:handle_post() in 32bit mode.
+
+On coreboot, the build arranges for romlayout.S:entry_elf() to be
+called in 32bit mode. This then calls post.c:handle_post().
+
+On CSM, the build arranges for romlayout.S:entry_csm() to be called
+(in 16bit mode). This then calls csm.c:handle_csm() in 32bit mode.
+Unlike on the emulators and coreboot, the SeaBIOS CSM POST phase is
+orchastrated with UEFI and there are several calls back and forth
+between SeaBIOS and UEFI via handle_csm() throughout the POST
+process.
+
+The POST phase itself has several sub-phases.
+
+* The "preinit" sub-phase: code run prior to code relocation.
+* The "init" sub-phase: code to initialize internal variables and
+ interfaces.
+* The "setup" sub-phase: code to setup hardware and drivers.
+* The "prepboot" sub-phase: code to finalize interfaces and prepare
+ for the boot phase.
+
+At completion of the POST phase, SeaBIOS invokes an "int 0x19"
+software interrupt in 16bit mode which begins the boot phase.
+
+Boot phase
+----------
+
+The goal of the boot phase is to load the first portion of the
+operating system's boot loader into memory and start execution of that
+boot loader. This phase starts when a software interrupt ("int 0x19"
+or "int 0x18") is invoked. The code flow starts in 16bit mode in
+romlayout.S:entry_19() or romlayout.S:entry_18() which then
+transition to 32bit mode and call boot.c:handle_19() or
+boot.c:handle_18().
+
+The boot phase is technically also part of the "runtime" phase of
+SeaBIOS. It is typically invoked immiediately after the POST phase,
+but it can also be invoked by an operating system or be invoked
+multiple times in an attempt to find a valid boot media. Although the
+boot phase C code runs in 32bit mode it does not have write access to
+the 0x0f0000-0x100000 memory region and can not call the various
+malloc_X() calls. See [Memory Model](Memory Model) for
+more information.
+
+Main runtime phase
+------------------
+
+The main runtime phase occurs after the boot phase starts the
+operating system. Once in this phase, the SeaBIOS code may be invoked
+by the operating system using various 16bit and 32bit calls. The goal
+of this phase is to support these legacy calling interfaces and to
+provide compatibility with BIOS standards. There are multiple entry
+points for the BIOS - see the entry_XXX() assembler functions in
+romlayout.S.
+
+Callers use most of these legacy entry points by setting up a
+particular CPU register state, invoking the BIOS, and then inspecting
+the returned CPU register state. To handle this, SeaBIOS will backup
+the current register state into a "struct bregs" (see romlayout.S,
+entryfuncs.S, and bregs.h) on call entry and then pass this struct to
+the C code. The C code can then inspect the register state and modify
+it. The assembler entry functions will then restore the (possibly
+modified) register state from the "struct bregs" on return to the
+caller.
+
+Resume and reboot
+-----------------
+
+As noted above, on emulators SeaBIOS handles the 0xFFFF0000:FFF0
+machine startup execution vector. This vector is also called on
+machine faults and on some machine "resume" events. It can also be
+called (as 0xF0000:FFF0) by software as a request to reboot the
+machine (on emulators, coreboot, and CSM).
+
+The SeaBIOS "resume and reboot" code handles these calls and attempts
+to determine the desired action of the caller. Code flow starts in
+16bit mode in romlayout.S:reset_vector() which calls
+romlayout.S:entry_post() which calls romlayout.S:entry_resume() which
+calls resume.c:handle_resume(). Depending on the request the
+handle_resume() code may transition to 32bit mode.
+
+Technically this code is part of the "runtime" phase, so even though
+parts of it run in 32bit mode it still has the same limitations of the
+runtime phase.
+
+Threads
+=======
+
+Internally SeaBIOS implements a simple cooperative multi-tasking
+system. The system works by giving each "thread" its own stack, and
+the system round-robins between these stacks whenever a thread issues
+a yield() call. This "threading" system may be more appropriately
+described as [coroutines](http://en.wikipedia.org/wiki/Coroutine).
+These "threads" do not run on multiple CPUs and are not preempted, so
+atomic memory accesses and complex locking is not required.
+
+The goal of these threads is to reduce overall boot time by
+parallelizing hardware delays. (For example, by allowing the wait for
+an ATA harddrive to spinup and respond to commands to occur in
+parallel with the wait for a PS/2 keyboard to respond to a setup
+command.) These hardware setup threads are only available during the
+"setup" sub-phase of the [POST phase](#POST_phase).
+
+The code that implements threads is in stacks.c.
+
+Hardware interrupts
+===================
+
+The SeaBIOS C code always runs with hardware interrupts disabled. All
+of the C code entry points (see romlayout.S) are careful to explicitly
+disable hardware interrupts (via "cli"). Because running with
+interrupts disabled increases interrupt latency, any C code that could
+loop for a significant amount of time (more than about 1 ms) should
+periodically call yield(). The yield() call will briefly enable
+hardware interrupts to occur, then disable interrupts, and then resume
+execution of the C code.
+
+There are two main reasons why SeaBIOS always runs C code with
+interrupts disabled. The first reason is that external software may
+override the default SeaBIOS handlers that are called on a hardware
+interrupt event. Indeed, it is common for DOS based applications to do
+this. These legacy third party interrupt handlers may have
+undocumented expections (such as stack location and stack size) and
+may attempt to call back into the various SeaBIOS software services.
+Greater compatibility and more reproducible results can be achieved by
+only permitting hardware interrupts at specific points (via yield()
+calls). The second reason is that much of SeaBIOS runs in 32bit mode.
+Attempting to handle interrupts in both 16bit mode and 32bit mode and
+switching between modes to delegate those interrupts is an unneeded
+complexity. Although disabling interrupts can increase interrupt
+latency, this only impacts legacy systems where the small increase in
+interrupt latency is unlikely to be noticeable.
+
+Extra 16bit stack
+=================
+
+SeaBIOS implements 16bit real mode handlers for both hardware
+interrupts and software request "interrupts". In a traditional BIOS,
+these requests would use the caller's stack space. However, the
+minimum amount of space the caller must provide has not been
+standardized and very old DOS programs have been observed to allocate
+very small amounts of stack space (100 bytes or less).
+
+By default, SeaBIOS now switches to its own stack on most 16bit real
+mode entry points. This extra stack space is allocated in ["low
+memory"](Memory Model). It ensures SeaBIOS uses a minimal amount of a
+callers stack (typically no more than 16 bytes) for these legacy
+calls. (More recently defined BIOS interfaces such as those that
+support 16bit protected and 32bit protected mode calls standardize a
+minimum stack size with adequete space, and SeaBIOS generally will not
+use its extra stack in these cases.)
+
+The code to implement this stack "hopping" is in romlayout.S and in
+stacks.c.

+This page describes the process that the SeaBIOS build uses to link
+the compiled code into the final binary objects.
+
+Unfortunately, the SeaBIOS linking phase is complex. This complexity
+is due to several unusual requirements:
+
+* Some BIOS entry points must reside at specific hardcoded memory
+ locations. The build must support positioning code and variables at
+ specific locations.
+* In order to support multiple [memory models](Memory Model) the same
+ C code can be complied in three modes (16bit mode, 32bit segmented
+ mode, and 32bit "flat" mode). Binary code from these three modes
+ must be able to co-exist and on occasion reference each other.
+* There is a finite amount of memory available to the BIOS. The build
+ will attempt to weed out unused code and variables from the final
+ binary. It also supports self-relocation of one-time initialization
+ code.
+
+Code layout
+===========
+
+To support the unusual build requirements, several
+[gcc](http://en.wikipedia.org/wiki/GNU_Compiler_Collection) compiler
+options are used. The "-ffunction-sections" and "-fdata-sections"
+flags instruct the compiler to place each variable and function into
+its own
+[ELF](http://en.wikipedia.org/wiki/Executable_and_Linkable_Format)
+section.
+
+The C code is compiled three times into three separate objects for
+each of the major supported [memory models](Memory Model):
+**code16.o**, **code32seg.o**, and **code32flat.o**. Information on
+the sections and symbols of these three objects are extracted (using
+**objdump**) and passed in to the **scripts/layoutrom.py** python
+script. This script analyzes this information and produces gnu
+[ld](http://en.wikipedia.org/wiki/GNU_linker) "linker scripts" which
+provide precise location information to the linker. These linker
+scripts are then used during the link phase which produces a **rom.o**
+object containing all the code.
+
+Fixed location entry points
+---------------------------
+
+The build supports placing code entry points and variables at fixed
+memory locations. This support is required in order to support the
+legacy BIOS standards. For example, a program might execute an "int
+0x15" to request system information from the BIOS, but another old
+program might use "ljmpw $0xf000, $0xf859" instead. Both must provide
+the same results and so the build must position the 0x15 interrupt
+entry point in physical memory at 0xff859.
+
+This support is accomplished by placing the given code/variables into
+ELF sections that have a name containing the substring
+".fixedaddr.0x1234" (where 0x1234 is the desired address). For
+variables in C code this is accomplished by marking the variables with
+the VARFSEGFIXED(0x1234) macro. For assembler entry points the ORG
+macro is used (see **romlayout.S**).
+
+During the build, the **layoutrom.py** script will detect sections
+that contain the ".fixedaddr." substring and will arrange for the
+final linker scripts to specify the desired address for the given
+section.
+
+Due to the sparse nature of these fixed address sections, the
+layoutrom.py script will also arrange to pack in other unrelated 16bit
+code into the free space between fixed address sections (see
+layoutrom.py:fitSections()). This maximizes the space available and
+reduces the overall size of the final binary.
+
+C code in three modes
+---------------------
+
+SeaBIOS must support multiple [memory models](Memory Model). This is
+accomplished by compiling the C code three separate times into three
+separate objects.
+
+The C code within a mode must not accidentally call a C function in
+another mode, but multiple modes must all access the same single copy
+of global variables. Further, it is occasionally necessary for the C
+code in one mode to obtain the address of C code in another mode.
+
+In order to use the same global variables between all modes, the
+layoutrom.py script will detect references to global variables and
+emit specific symbol definitions for those global variables in the
+linker scripts so that all references use the same physical memory
+address (see layoutrom.py:outXRefs()).
+
+To ensure C code does not accidentally call C code compiled in a
+different mode, the build will ensure the symbols for C code in each
+mode are isolated from each other during the linking stage. To support
+those situations where an address of a C function in another mode is
+required the build supports symbols with a special "\_cfuncX_"
+prefix. The layoutrom.py script detects these references and will emit
+a corresponding symbol definitions in the linker script that points to
+the C code of the specified mode. This is typically seen with code
+like:
+
+`extern void _cfunc32flat_process_op(void);`\
+`return call32(_cfunc32flat_process_op, 0, 0);`
+
+In the above example, when the build finds the symbol
+"\_cfunc32flat_process_op" it will emit that symbol with the physical
+address of the 32bit "flat" version of the process_op() C function.
+
+Build garbage collection
+------------------------
+
+To reduce the overall size of the final SeaBIOS binary the build
+supports automatically weeding out of unused code and variables. This
+is done with two separate processes: when supported the gcc
+"-fwhole-program" compilation flag is used, and the layoutrom.py
+script checks for unreferenced ELF sections. The layoutrom.py script
+builds the final linker scripts with only referenced ELF sections, and
+thus unreferenced sections are weeded out from the final objects.
+
+When writing C code, it is necessary to mark C functions with the
+VISIBLE16, VISIBLE32SEG, or VISIBLE32FLAT macros if the functions are
+ever referenced from assembler code. These macros ensure the
+corresponding C function is emitted by the C compiler when compiling
+for the given memory mode. These macros, however, do not affect the
+layoutrom.py reference check, so even a function decorated with one of
+the above macros can be weeded out from the final object if it is
+never referenced.
+
+Code relocation
+---------------
+
+To further reduce the runtime memory size of the BIOS, the build
+supports runtime self-relocation. Normally SeaBIOS is loaded into
+memory in the memory region at 0xC0000-0x100000. This is convenient
+for initial binary deployment, but the space competes with memory
+requirements for Option ROMs, BIOS tables, and runtime storage. By
+default, SeaBIOS will self-relocate its one-time initialization code
+to free up space in this region.
+
+To support this feature, the build attempts to automatically detect
+which C code is exclusively initialization phase code (see
+layoutrom.py:checkRuntime()). It does this by finding all functions
+decorated with the VISIBLE32INIT macro and all functions only
+reachable via functions with that macro. These "init only" functions
+are then grouped together and their location and size is stored in the
+binary for the runtime code to relocate (see post.c:reloc_preinit()).
+
+The build also locates all cross section code references along with
+all absolute memory addresses in the "init only" code. These addresses
+need to be modified with the new run-time address in order for the
+code to successfully run at a new address. The build finds the
+location of the addresses (see layoutrom.py:getRelocs()) and stores
+the information in the final binary.
+
+Final binary checks
+===================
+
+At the conclusion of the main linking stage, the code is contained in
+the file **rom.o**. This object file contains all of the assembler
+code, variables, and the C code from all three memory model modes.
+
+At this point the **scripts/checkrom.py** script is run to perform
+final checks on the code. The script performs some sanity checks, it
+may update some tables in the binary, and it reports some size
+information.
+
+After the checkrom.py script is run the final user visible binary is
+produced. The name of the final binary is either **bios.bin**,

+The SeaBIOS code is required to support multiple x86 CPU memory
+models. This requirement impacts the code layout and internal storage
+of SeaBIOS.
+
+x86 Memory Models
+=================
+
+The x86 line of CPUs has evolved over many years. The original 8086
+chip used 16bit pointers and could only address 1 megabyte of memory.
+The 80286 CPU still used 16bit pointers, but could address up to 16
+megabytes of memory. The 80386 chips could process 32bit instructions
+and could access up to 4 gigabyte of memory. The most recent x86 chips
+can process 64bit instructions and access 16 exabytes of ram.
+
+During the evolution of the x86 CPUs from the 8086 to the 80386 the
+BIOS was extended to handle calls in the various modes that the CPU
+implemented.
+
+This section outlines the five different x86 CPU execution and memory
+access models that SeaBIOS supports.
+
+16bit real mode
+---------------
+
+This mode is a
+[segmented](http://en.wikipedia.org/wiki/Memory_segmentation) memory
+mode invoked by callers. The CPU defaults to executing 16bit
+instructions. Callers typically invoke the BIOS by issuing an "int x"
+instruction which causes a software
+[interrupt](http://en.wikipedia.org/wiki/Interrupt) that is handled by
+the BIOS. The SeaBIOS code also handles hardware interrupts in this
+mode. SeaBIOS can only access the first 1 megabyte of memory in this
+mode, but it can access any part of that first megabyte.
+
+16bit bigreal mode
+------------------
+
+This mode is a segmented memory mode that is used for [option
+roms](http://en.wikipedia.org/wiki/Option_ROM). The CPU defaults to
+executing 16bit instructions and segmented memory accesses are still
+used. However, the segment limits are increased so that the entire
+first 4 gigabytes of memory is fully accessible. Callers can invoke
+all the [16bit real mode](#16bit_real_mode) functions while in this
+mode and can also invoke the Post Memory Manager (PMM) functions that
+are available during option rom execution.
+
+16bit protected mode
+--------------------
+
+CPU execution in this mode is similar to [16bit real
+mode](#16bit_real_mode). The CPU defaults to executing 16bit
+instructions. However, each segment register indexes a "descriptor
+table", and it is difficult or impossible to know what the physical
+address of each segment is. Generally speaking, the BIOS can only
+access code and data in the f-segment. The PCIBIOS, APM BIOS, and PNP
+BIOS all have documented 16bit protected mode entry points.
+
+Some old code may attempt to invoke the standard [16bit real
+mode](#16bit_real_mode) entry points while in 16bit protected
+mode. The PCI BIOS specification explicitly requires that the legacy
+"int 1a" real mode entry point support 16bit protected mode calls if
+they are for the PCI BIOS. Callers of other legacy entry points in
+protected mode have not been observed and SeaBIOS does not support
+them.
+
+32bit segmented mode
+--------------------
+
+In this mode the processor runs in 32bit mode, but the segment
+registers may have a limit and may have a non-zero offset. In effect,
+this mode has all of the limitations of [16bit protected
+mode](#16bit_protected_mode) - the main difference between the modes
+is that the processor defaults to executing 32bit instructions. In
+addition to these limitations, callers may also run the SeaBIOS code
+at varying virtual addresses and so the code must support code
+relocation. The PCI BIOS specification and APM BIOS specification
+define 32bit segmented mode interfaces.
+
+32bit flat mode
+---------------
+
+In this mode the processor defaults to executing 32bit instructions,
+and all segment registers have an offset of zero and allow access to
+the entire first 4 gigabytes of memory. This is the only "sane" mode
+for 32bit code - modern compilers and modern operating systems will
+generally only support this mode (when running 32bit code).
+Ironically, it's the only mode that is not strictly required for a
+BIOS to support. SeaBIOS uses this mode internally to support the POST
+and BOOT [phases of execution](Execution and code flow).
+
+code16gcc
+=========
+
+In order to produce code that can run when the processor is in a 16bit
+mode, SeaBIOS uses the
+[binutils](http://en.wikipedia.org/wiki/GNU_Binutils) ".code16gcc"
+assembler flag. This instructs the assembler to emit extra prefix
+opcodes so that the 32bit code produced by
+[gcc](http://en.wikipedia.org/wiki/GNU_Compiler_Collection) will run
+even when the processor is in 16bit mode. Note that gcc always
+produces 32bit code - it does not know about the ".code16gcc" flag and
+does not know that the code will run in a 16bit mode.
+
+SeaBIOS uses the same code for all of the 16bit modes ([16bit real
+mode](#16bit_real_mode), [16bit bigreal mode](#16bit_bigreal_mode),
+and [16bit protected mode](#16bit_protected_mode)) and that code is
+assembled using ".code16gcc". SeaBIOS is careful to use segment
+registers properly so that the same code can run in the different
+16bit modes that it needs to support.
+
+C code mode flags
+=================
+
+Two compile time flags are available to determine the memory model the
+code is intended for: MODE16 and MODESEGMENT. When compiling for the
+16 bit modes, MODE16 is true and MODESEGMENT is true. In 32bit
+segmented mode, MODE16 is false and MODESEGMENT is true. In 32bit flat
+mode both MODE16 and MODESEGMENT are false.
+
+Common memory used at run-time
+==============================
+
+There are several memory areas that the SeaBIOS "runtime"
+[phase](Execution and code flow) makes use of:
+
+* 0x000000-0x000400: Interrupt descriptor table (IDT). This area
+ defines 256 interrupt vectors as defined by the Intel CPU
+ specification for 16bit irq handlers. This area is read/writable at
+ runtime and can be accessed from 16bit real mode and 16bit bigreal
+ mode calls. SeaBIOS only uses this area to maintain compatibility
+ with legacy systems.
+
+* 0x000400-0x000500: BIOS Data Area (BDA). This area contains various
+ legacy flags and attributes. The area is read/writable at runtime
+ and can be accessed from 16bit real mode and 16bit bigreal mode
+ calls. SeaBIOS only uses this area to maintain compatibility with
+ legacy systems.
+
+* 0x09FC00-0x0A0000 (typical): Extended BIOS Data Area (EBDA). This
+ area contains a few legacy flags and attributes. The area is
+ typically located at 0x9FC00, but it can be moved by option roms, by
+ legacy operating systems, and by SeaBIOS if
+ CONFIG_MALLOC_UPPERMEMORY is not set. Its actual location is
+ determined by a pointer in the BDA. The area is read/writable at
+ runtime and can be accessed from 16bit real mode and 16bit bigreal
+ mode calls. SeaBIOS only uses this area to maintain compatibility
+ with legacy systems.
+
+* 0x0E0000-0x0F0000 (typical): "low" memory. This area is used for
+ custom read/writable storage internal to SeaBIOS. The area is
+ read/writable at runtime and can be accessed from 16bit real mode
+ and 16bit bigreal mode calls. The area is typically located at the
+ end of the e-segment, but the build may position it anywhere in the
+ 0x0C0000-0x0F0000 region. However, if CONFIG_MALLOC_UPPERMEMORY is
+ not set, then this region is between 0x090000-0x0A0000. Space is
+ allocated in this region by either marking a global variable with
+ the "VARLOW" flag or by calling malloc_low() during
+ initialization. The area can be grown dynamically (via malloc_low),
+ but it will never exceed 64K.
+
+* 0x0F0000-0x100000: The BIOS segment. This area is used for both
+ runtime code and static variables. Space is allocated in this region
+ by either marking a global variable with VAR16, one of the VARFSEG
+ flags, or by calling malloc_fseg() during initialization. The area
+ is read-only at runtime and can be accessed from 16bit real mode,
+ 16bit bigreal mode, 16bit protected mode, and 32bit segmented mode
+ calls.
+
+All of the above areas are also read/writable during the SeaBIOS
+initialization phase and are accessible when in 32bit flat mode.
+
+Segmented mode memory access
+============================
+
+The assembler entry functions for segmented mode calls (all modes
+except [32bit flat mode](#32bit_flat_mode)) will arrange
+to set the data segment (%ds) to be the same as the stack segment
+(%ss) before calling any C code. This permits all C variables located
+on the stack and C pointers to data located on the stack to work as
+normal.
+
+However, all code running in segmented mode must wrap non-stack memory
+accesses in special macros. These macros ensure the correct segment
+register is used. Failure to use the correct macro will result in an
+incorrect memory access that will likely cause hard to find errors.
+
+There are three low-level memory access macros:
+
+* GET_VAR / SET_VAR : Accesses a variable using the specified segment
+ register. This isn't typically used directly by C code.
+
+* GET_FARVAR / SET_FARVAR : Assigns the extra segment (%es) to the
+ given segment id and then performs the given memory access via %es.
+
+* GET_FLATVAR / SET_FLATVAR : These macros take a 32bit pointer,
+ construct a segment/offset pair valid in real mode, and then perform
+ the given access. These macros must not be used in 16bit protected
+ mode or 32bit segmented mode.
+
+Since most memory accesses are to [common memory used at
+run-time](#Common_memory_used_at_run-time), several helper
+macros are also available.
+
+* GET_IDT / SET_IDT : Access the interrupt descriptor table (IDT).
+
+* GET_BDA / SET_BDA : Access the BIOS Data Area (BDA).
+
+* GET_EBDA / SET_EBDA : Access the Extended BIOS Data Area (EBDA).
+
+* GET_LOW / SET_LOW : Access internal variables marked with
+ VARLOW. (There are also related macros GET_LOWFLAT / SET_LOWFLAT for
+ accessing storage allocated with malloc_low).
+
+* GET_GLOBAL : Access internal variables marked with the VAR16 or
+ VARFSEG flags. (There is also the related macro GET_GLOBALFLAT for
+ accessing storage allocated with malloc_fseg).
+
+Memory available during initialization
+======================================
+
+During the POST [phase](Execution and code flow) the code
+can fully access the first 4 gigabytes of memory. However, memory
+accesses are generally limited to the [common memory used at
+run-time](#Common_memory_used_at_run-time) and areas
+allocated at runtime via one of the malloc calls:
+
+* malloc_high : Permanent high-memory zone. This area is used for
+ custom read/writable storage internal to SeaBIOS. The area is
+ located at the top of the first 4 gigabytes of ram. It is commonly
+ used for storing standard tables accessed by the operating system at
+ runtime (ACPI, SMBIOS, and MPTable) and for DMA buffers used by
+ hardware drivers. The area is read/writable at runtime and an entry
+ in the e820 memory map is used to reserve it. When running on an
+ emulator that has only 1 megabyte of ram this zone will be empty.
+
+* malloc_tmphigh : Temporary high-memory zone. This area is used for
+ custom read/writable storage during the SeaBIOS initialization
+ phase. The area generally starts after the first 1 megabyte of ram
+ (0x100000) and ends prior to the Permanent high-memory zone. When
+ running on an emulator that has only 1 megabyte of ram this zone
+ will be empty. The area is not reserved from the operating system,
+ so it must not be accessed after the SeaBIOS initialization phase.
+
+* malloc_tmplow : Temporary low-memory zone. This area is used for
+ custom read/writable storage during the SeaBIOS initialization
+ phase. The area resides between 0x07000-0x90000. The area is not
+ reserved from the operating system and by specification it is
+ required to be zero'd at the end of the initialization phase.
+
+The "tmplow" and "tmphigh" regions are only available during the
+initialization phase. Any access (either read or write) after
+completion of the initialization phase can result in difficult to find
+errors.

+SeaBIOS is an open source implementation of a 16bit X86 BIOS. SeaBIOS
+can run in an emulator or it can run natively on X86 hardware with the
+use of [coreboot](http://www.coreboot.org/).
+
+SeaBIOS is the default BIOS for [qemu](http://www.qemu.org/) and
+[kvm](http://www.linux-kvm.org/).
+
+The [coreboot SeaBIOS](http://www.coreboot.org/SeaBIOS) page has
+information on using SeaBIOS in coreboot. Please see the
+[releases](Releases) page for information on recent releases. See the
+[download](Download) page to obtain SeaBIOS.
+
+Please join the [mailing list](Mailinglist) to contribute to
+SeaBIOS. Information on the internals of SeaBIOS is available on the
+[Developer Documentation](Developer Documentation) page.

+# Locate and execute ACPI_EXTRACT directives, output offset info
+#
+# Documentation of ACPI_EXTRACT_* directive tags:
+#
+# These directive tags output offset information from AML for BIOS runtime
+# table generation.
+# Each directive is of the form:
+# ACPI_EXTRACT_<TYPE> <array_name> <Operator> (...)
+# and causes the extractor to create an array
+# named <array_name> with offset, in the generated AML,
+# of an object of a given type in the following <Operator>.
+#
+# A directive must fit on a single code line.
+#
+# Object type in AML is verified, a mismatch causes a build failure.
+#
+# Directives and operators currently supported are:
+# ACPI_EXTRACT_NAME_DWORD_CONST - extract a Dword Const object from Name()
+# ACPI_EXTRACT_NAME_WORD_CONST - extract a Word Const object from Name()
+# ACPI_EXTRACT_NAME_BYTE_CONST - extract a Byte Const object from Name()
+# ACPI_EXTRACT_METHOD_STRING - extract a NameString from Method()
+# ACPI_EXTRACT_NAME_STRING - extract a NameString from Name()
+# ACPI_EXTRACT_PROCESSOR_START - start of Processor() block
+# ACPI_EXTRACT_PROCESSOR_STRING - extract a NameString from Processor()
+# ACPI_EXTRACT_PROCESSOR_END - offset at last byte of Processor() + 1
+# ACPI_EXTRACT_DEVICE_START - start of Device() block
+# ACPI_EXTRACT_DEVICE_STRING - extract a NameString from Device()
+# ACPI_EXTRACT_DEVICE_END - offset at last byte of Device() + 1
+# ACPI_EXTRACT_PKG_START - start of Package block
+#
+# ACPI_EXTRACT_ALL_CODE - create an array storing the generated AML bytecode
+#
+# ACPI_EXTRACT is not allowed anywhere else in code, except in comments.

+/*
+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different configurations.\n"
+"\n"
+"The <Save> button will let you save the current configuration to\n"
+"a file of your choosing. Use the <Load> button to load a previously\n"
+"saved alternate configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you find\n"
+"during a Menuconfig session that you have completely messed up your\n"
+"settings, you may use the <Load> button to restore your previously\n"
+"saved settings from \".config\" without restarting Menuconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use Menuconfig in an XTERM window, make sure you have your\n"
+"$TERM variable set to point to an xterm definition which supports\n"
+"color. Otherwise, Menuconfig will look rather bad. Menuconfig will\n"
+"not display correctly in an RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry. I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment. Some distributions\n"
+"export those variables via /etc/profile. Some ncurses programs can\n"
+"become confused when those variables (LINES & COLUMNS) don't reflect\n"
+"the true screen size.\n"
+"\n"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the options listed in a single menu,\n"
+"rather than the default multimenu hierarchy, run the menuconfig with\n"
+"MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"
+"\n"
+"Note that this mode can eventually be a little more CPU expensive\n"
+"(especially with a larger number of unrolled categories) than the\n"
+"default mode.\n"
+"\n"
+"Different color themes available\n"
+"--------------------------------\n"
+"It is possible to select different color themes using the variable\n"
+"MENUCONFIG_COLOR. To select a theme use:\n"
+"\n"
+"make MENUCONFIG_COLOR=<theme> menuconfig\n"
+"\n"
+"Available themes are\n"
+" mono => selects colors suitable for monochrome displays\n"
+" blackbg => selects a color scheme with black background\n"
+" classic => theme with blue background. The classic look\n"
+" bluetitle => an LCD friendly version of classic. (default)\n"

+# It's simple enough to figure out how this works.
+# If not, then you can ask me at stripconfig@goodmis.org
+#
+# What it does?
+#
+# If you have installed a Linux kernel from a distribution
+# that turns on way too many modules than you need, and
+# you only want the modules you use, then this program
+# is perfect for you.
+#
+# It gives you the ability to turn off all the modules that are
+# not loaded on your system.
+#
+# Howto:
+#
+# 1. Boot up the kernel that you want to stream line the config on.
+# 2. Change directory to the directory holding the source of the
+# kernel that you just booted.
+# 3. Copy the configuraton file to this directory as .config
+# 4. Have all your devices that you need modules for connected and
+# operational (make sure that their corresponding modules are loaded)
+# 5. Run this script redirecting the output to some other file
+# like config_strip.
+# 6. Back up your old config (if you want too).
+# 7. copy the config_strip file to .config
+# 8. Run "make oldconfig"
+#
+# Now your kernel is ready to be built with only the modules that
+# are loaded.
+#
+# Here's what I did with my Debian distribution.
+#
+# cd /usr/src/linux-2.6.10
+# cp /boot/config-2.6.10-1-686-smp .config
+# ~/bin/streamline_config > config_strip

+ - The only way there can be no lookahead present (in yychar) is if

+ detecting the absence of a lookahead is sufficient to determine
+ that there is no unexpected or expected token to report. In that
+ case, just report a simple "syntax error".
+ - Don't assume there isn't a lookahead just because this state is a
+ consistent state with a default action. There might have been a
+ previous inconsistent state, consistent state with a non-default
+ action, or user semantic action that manipulated yychar.
+ - Of course, the expected token list depends on states to have
+ correct lookahead information, and it depends on the parser not
+ to perform extra reductions after fetching a lookahead from the
+ scanner and before detecting a syntax error. Thus, state merging
+ (from LALR or IELR) and default reductions corrupt the expected
