-=head1 NAME
-
-get_abi.pl - parse the Linux ABI files and produce a ReST book.
-
-=head1 SYNOPSIS
-
-B<get_abi.pl> [--debug <level>] [--enable-lineno] [--man] [--help]
- [--(no-)rst-source] [--dir= ] [--show-hints]
- [--search-string <regex>]
- <COMMAND> [<ARGUMENT>]
-
-Where B<COMMAND> can be:
-
-=over 8
-
-B<search> I<SEARCH_REGEX> - search for I<SEARCH_REGEX> inside ABI
-
-B<rest> - output the ABI in ReST markup language
-
-B<validate> - validate the ABI contents
-
-B<undefined> - existing symbols at the system that aren't
- defined at Documentation/ABI
-
-=back
-
-=head1 OPTIONS
-
-=over 8
-
-=item B<--dir>
-
-Changes the location of the ABI search. By default, it uses
-the Documentation/ABI directory.
-
-=item B<--rst-source> and B<--no-rst-source>
-
-The input file may be using ReST syntax or not. Those two options allow
-selecting between a rst-compliant source ABI (B<--rst-source>), or a
-plain text that may be violating ReST spec, so it requres some escaping
-logic (B<--no-rst-source>).
-
-=item B<--enable-lineno>
-
-Enable output of .. LINENO lines.
-
-=item B<--debug> I<debug level>
-
-Print debug information according with the level, which is given by the
-following bitmask:
-
- - 1: Debug parsing What entries from ABI files;
- - 2: Shows what files are opened from ABI files;
- - 4: Dump the structs used to store the contents of the ABI files.
-
-=item B<--show-hints>
-
-Show hints about possible definitions for the missing ABI symbols.
-Used only when B<undefined>.
-
-=item B<--search-string> I<regex string>
-
-Show only occurences that match a search string.
-Used only when B<undefined>.
-
-=item B<--help>
-
-Prints a brief help message and exits.
-
-=item B<--man>
-
-Prints the manual page and exits.

-
-=head1 DESCRIPTION
-
-Parse the Linux ABI files from ABI DIR (usually located at Documentation/ABI),
-allowing to search for ABI symbols or to produce a ReST book containing
-the Linux ABI documentation.
-
-=head1 EXAMPLES
-
-Search for all stable symbols with the word "usb":
-
-=over 8
-
-$ scripts/get_abi.pl search usb --dir Documentation/ABI/stable
-
-=back
-
-Search for all symbols that match the regex expression "usb.*cap":
-
-=over 8
-
-$ scripts/get_abi.pl search usb.*cap
-
-=back
-
-Output all obsoleted symbols in ReST format
-
-=over 8
-
-$ scripts/get_abi.pl rest --dir Documentation/ABI/obsolete
-
-=back
