 =head1 DESCRIPTION
 
 C<OpenBSD::Mtree> is a parser for C<mtree(8)> specifications that
 can reconstruct directory hierarchies.
 
-The basic function C<OpenBSD::Mtree::parse_fh(\%hash, $basedir, $fh)>
+The basic function C<OpenBSD::Mtree::parse_fh(\%hash, $basedir, $fh, $extra)>
 will populate the hash C<$hash> with defined entries for each directory
 seen while reading from C<$fh>, assuming the specification is to be interpreted
 relative to C<$basedir> (some canonicalization of directory names will
 occur).
 
-C<OpenBSD::Mtree:parse(\%hash, $basedir, $filename)> is a convenience
+If C<$extra> is non null, each entry will itself be an empty hash.
+
+C<OpenBSD::Mtree:parse(\%hash, $basedir, $filename, $extra)> is a convenience
 function which also handles opening the filehandle from C<$filename>
 and closing it after reading the specification.
