+=head1 NAME
+
+abi_book.pl - parse the Linux ABI files and produce a ReST book.
+
+=head1 SYNOPSIS
+
+B<abi_book.pl> [--debug] [--man] [--help] [--dir=<dir>] <COMAND> [<ARGUMENT>]
+
+Where <COMMAND> can be:
+
+=over 8
+
+B<search> [SEARCH_REGEX] - search for [SEARCH_REGEX] inside ABI
+
+B<rest> - output the ABI in ReST markup language
+
+B<validate> - validate the ABI contents
+
+=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<--debug>
+
+Put the script in verbose mode, useful for debugging. Can be called multiple
+times, to increase verbosity.
+
+=item B<--help>
+
+Prints a brief help message and exits.
+
+=item B<--man>
+
+Prints the manual page and exits.
+
+=back
+
+=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
+
