NAME
       guards -	select from a list of files guarded by conditions

SYNOPSIS
       guards [--prefix=dir] [--path=dir1:dir2:...] [--default=<0|1>]
       [--check|--list]	[--invert-match] [--with-guards] [--config=<file>]
       symbol ...

DESCRIPTION
       The script reads	a configuration	file that may contain so-called
       guards, file names, and comments, and writes those file names that
       satisfy all guards to standard output. The script takes a list of
       symbols as its arguments. Each line in the configuration	file is
       processed separately. Lines may start with a number of guards. The
       following guards	are defined:

	   +xxx	Include	the file(s) on this line if the	symbol xxx is defined.

	   -xxx	Exclude	the file(s) on this line if the	symbol xxx is defined.

	   +!xxx Include the file(s) on	this line if the symbol	xxx is not
	   defined.

	   -!xxx Exclude the file(s) on	this line if the symbol	xxx is not
	   defined.

	   - Exclude this file.	Used to	avoid spurious --check messages.

       The guards are processed	left to	right. The last	guard that matches
       determines if the file is included. If no guard is specified, the
       --default setting determines if the file	is included.

       If no configuration file	is specified, the script reads from standard
       input.

       The --check option is used to compare the specification file against
       the file	system.	If files are referenced	in the specification that do
       not exist, or if	files are not enlisted in the specification file
       warnings	are printed. The --path	option can be used to specify which
       directory or directories	to scan.  Multiple directories are separated
       by a colon (":")	character. The --prefix	option specifies the location
       of the files. Alternatively, the	--path=@_file_ syntax can be used to
       specify a file from which the file names	will be	read.

       Use --list to list all files independent	of any rules. Use
       --invert-match to list only the excluded	patches. Use --with-guards to
       also include all	inclusion and exclusion	rules.
