+.SH SYNOPSIS
+.B cpabe-keygen
+[\fIOPTION \fR...] \fIPUB_KEY MASTER_KEY ATTR \fR[\fIATTR \fR...]
+.SH DESCRIPTION
+Generate a key with the listed attributes using public key PUB_KEY and
+master secret key MASTER_KEY. Output will be written to the file
+"priv_key" unless the \fB\-o\fR option is specified.
+.PP
+Attributes come in two forms: non\-numerical and numerical. Non\-numerical
+attributes are simply any string of letters, digits, and underscores
+beginning with a letter.
+.PP
+Numerical attributes are specified as `attr = N', where N is a non\-negative
+integer less than 2^64 and `attr' is another string. The whitespace around
+the `=' is optional. One may specify an explicit length of k bits for the
+integer by giving `attr = N#k'. Note that any comparisons in a policy given
+to cpabe\-enc(1) must then specify the same number of bits, e.g.,
+`attr > 5#12'.
+.PP
+The keywords `and', `or', and `of', are reserved for the policy language
+of cpabe\-enc (1) and may not be used for either type of attribute.
+.PP
+Mandatory arguments to long options are mandatory for short options too.

+.SH EXAMPLES
+
+Generating a key for a new employee Sara:
+
+  $ cpabe-keygen -o sara_priv_key pub_key master_key \\
+.br
+      sysadmin it_department
+
+Generating a key with more complicated attributes:
+
+  $ cpabe-keygen -o kevin_priv_key pub_key master_key \\
+.br
+      business_staff strategy_team 'executive_level = 7#4' \\
+.br
+      office=2362 'hire_date = '`date +%s`
+
+Note the usage of date (1) as a convenient way of storing a time in a
+numerical attribute.
