-MAINTAINER field selection options:
-  --email => print email address(es) if any
-    --git => include recent git \*-by: signers
-    --git-all-signature-types => include signers regardless of signature type
-        or use only ${signature_pattern} signers (default: $email_git_all_signature_types)
-    --git-fallback => use git when no exact MAINTAINERS pattern (default: $email_git_fallback)
-    --git-min-signatures => number of signatures required (default: $email_git_min_signatures)
-    --git-max-maintainers => maximum maintainers to add (default: $email_git_max_maintainers)
-    --git-min-percent => minimum percentage of commits required (default: $email_git_min_percent)
-    --git-blame => use git blame to find modified commits for patch or file
-    --git-since => git history to use (default: $email_git_since)
-    --hg-since => hg history to use (default: $email_hg_since)
-    --interactive => display a menu (mostly useful if used with the --git option)
-    --m => include maintainer(s) if any
-    --n => include name 'Full Name <addr\@domain.tld>'
-    --l => include list(s) if any
-    --s => include subscriber only list(s) if any
-    --remove-duplicates => minimize duplicate email names/addresses
-    --roles => show roles (status:subsystem, git-signer, list, etc...)
-    --rolestats => show roles and statistics (commits/total_commits, %)
-    --file-emails => add email addresses found in -f file (default: 0 (off))
-  --scm => print SCM tree(s) if any
-  --status => print status if any
-  --subsystem => print subsystem name if any
-  --web => print website(s) if any
-
-Output type options:
-  --separator [, ] => separator for multiple entries on 1 line
-    using --separator also sets --nomultiline if --separator is not [, ]
-  --multiline => print 1 entry per line
-
-Other options:
-  --pattern-depth => Number of pattern directory traversals (default: 0 (all))
-  --keywords => scan patch for keywords (default: $keywords)
-  --sections => print all of the subsystem sections with pattern matches
-  --mailmap => use .mailmap file (default: $email_use_mailmap)
-  --version => show version
-  --help => show this help information
-
-Default options:
-  [--email --nogit --git-fallback --m --n --l --multiline -pattern-depth=0
-   --remove-duplicates --rolestats]
-
-Notes:
-  Using "-f directory" may give unexpected results:
-      Used with "--git", git signators for _all_ files in and below
-          directory are examined as git recurses directories.
-          Any specified X: (exclude) pattern matches are _not_ ignored.
-      Used with "--nogit", directory is used as a pattern match,
-          no individual file within the directory or subdirectory
-          is matched.
-      Used with "--git-blame", does not iterate all files in directory
-  Using "--git-blame" is slow and may add old committers and authors
-      that are no longer active maintainers to the output.
-  Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
-      other automated tools that expect only ["name"] <email address>
-      may not work because of additional output after <email address>.
-  Using "--rolestats" and "--git-blame" shows the #/total=% commits,
-      not the percentage of the entire file authored.  # of commits is
-      not a good measure of amount of code authored.  1 major commit may
-      contain a thousand lines, 5 trivial commits may modify a single line.
-  If git is not installed, but mercurial (hg) is installed and an .hg
-      repository exists, the following options apply to mercurial:
-          --git,
-          --git-min-signatures, --git-max-maintainers, --git-min-percent, and
-          --git-blame
-      Use --hg-since not --git-since to control date selection
-  File ".get_maintainer.conf", if it exists in the QEMU source root
-      directory, can change whatever get_maintainer defaults are desired.
-      Entries in this file can be any command line argument.
-      This file is prepended to any additional command line arguments.
-      Multiple lines and # comments are allowed.
