This resource finds arbitrary documentation on the filesystem.


=head2 C<file_index>

This method doesn't return anything useful yet.

=head2 C<file_fetch>

Takes a module name, program name, or Pod page name. Since the details of
C<$PERL6LIB> are still fuzzy, it currently just returns the contents of
the supplied file.

=head2 C<file_locate>

Returns the filename given if it is a real file. Not very useful.
