=head1 NAME

App::Greple::type - file type filter module for greple

=head1 SYNOPSIS

    greple -Mdig -Mtype --type-xxxx ... --dig .

=head1 VERSION

Version 1.01

=head1 DESCRIPTION

This module filters search target files by given rule.  It is
convenient to use with other B module which support recursive
or multi-file search such as B<-Mfind>, B<-Mdig> or B<-Mgit>.

For example, option for Perl is defined as this:

    option --type-perl \
           --suffix=pl,PL,pm,pod,t,psgi \
           --shebang=perl

Using this option, only files those name end with B<--suffix> option
or files which contains string C in the first C<#!> (shebang)
line will be searched.

Option B<--suffix> and B<--shebang> are defined in
L module.

=head1 SHORT NAME

Calling module as B<-Mtype::config(short)> or B<-Mtype::config=short>
introduce short name for rule options.  When short name mode is
activated, all B<--type-xxxx> options can be used as B<--xxxx> as
well.

=head1 BACKGROUND

This module is inspired by L command, and original matching
rule is taken from it.

Filename matching can be done with B<-Mfind> module, but to know file
type from its content, different mechanism was required.  So I made
the B<--begin> function can die to stop the file processing, and
introduced new B<-Mselect> module.
