=head1 NAME

get_feat.pl - parse the Linux Feature files and produce a ReST book.

=head1 SYNOPSIS

B<get_feat.pl> [--debug] [--man] [--help] [--dir=<dir>] [--arch=<arch>]
	       [--feature=<feature>|--feat=<feature>] <COMAND> [<ARGUMENT>]

Where <COMMAND> can be:

=over 8

B<current>               - output table in ReST compatible ASCII format
			   with features for this machine's architecture

B<rest>                  - output table(s)  in ReST compatible ASCII format
			   with features in ReST markup language. The output
			   is affected by --arch or --feat/--feature flags.

B<validate>              - validate the contents of the files under
			   Documentation/features.

B<ls> or B<list>         - list features for this machine's architecture,
			   using an easier to parse format.
			   The output is affected by --arch flag.

=back

=head1 OPTIONS

=over 8

=item B<--arch>

Output features for an specific architecture, optionally filtering for
a single specific feature.

=item B<--feat> or B<--feature>

Output features for a single specific feature.

=item B<--dir>

Changes the location of the Feature files. By default, it uses
the Documentation/features directory.

=item B<--enable-fname>

Prints the file name of the feature files. This can be used in order to
track dependencies during documentation build.

=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 feature files from Documentation/features (by default),
optionally producing results at ReST format.

It supports output data per architecture, per feature or a
feature x arch matrix.

When used with B<rest> command, it will use either one of the tree formats:

If neither B<--arch> or B<--feature> arguments are used, it will output a
matrix with features per architecture.

If B<--arch> argument is used, it will output the features availability for
a given architecture.

If B<--feat> argument is used, it will output the content of the feature
file using ReStructured Text markup.
