=head1 SYNOPSIS
In your .conf:
<Controller::Foo>
- cgi_root_path cgi-bin
- cgi_dir cgi-bin
+ cgi_root_path cgi-bin
+ cgi_dir cgi-bin
+ cgi_chain_root /optional/private/path/to/Chained/root
+ cgi_file_pattern *.cgi
+ # or regex
+ cgi_file_pattern /\.pl\z/
<CGI>
username_field username # used for REMOTE_USER env var
pass_env PERL5LIB
The global URI path prefix for CGIs, defaults to C<cgi-bin>.
+=head2 cgi_chain_root
+
+By default L<Path|Catalyst::DispatchType::Path> actions are created for CGIs,
+but if you specify this option, the actions will be created as
+L<Chained|Catalyst::DispatchType::Chained> end-points, chaining off the
+specified private path.
+
+If this option is used, the L</cgi_root_path> option is ignored. The root path
+will be determined by your chain.
+
+The L<PathPart|Catalyst::DispatchType::Chained/PathPart> of the action will be
+the path to the CGI file.
+
=head2 cgi_dir
Path from which to read CGI files. Can be relative to C<$MYAPP_HOME/root> or
absolute. Defaults to C<$MYAPP_HOME/root/cgi-bin>.
+=head2 cgi_file_pattern
+
+By default all files in L</cgi_dir> will be loaded as CGIs, however, with this
+option you can specify either a glob or a regex to match the names of files you
+want to be loaded.
+
+Can be an array of globs/regexes as well.
