=item * "i" makes the regexp case insensitive,

=item * "e" makes the match use string equality instead of regexp,

=item * "r" makes the match use regexp instead of string equality,

=item * "x" makes it an excluding filter

=back

=head1 OUTPUT STYLES

You can specify the output style with the -y option:

-y1 groups output by filename, with each matching line prepended
with it's line number. This is the default.

-y2 looks like classic grep output. Each line looks like file:line:match.

-y3 just has the matching line. This is the default for piped input.
goes well with the -p option sometimes.
