=item set_libdir $path

Sets the library directory to the given path
(default: $ENV{CROSSFIRE_LIBDIR}).

You have to (re-)load the archetypes and tilecache manually after steting
the library path.

=cut

sub set_libdir($) {
   $LIB = $_[0];

=item load_archetypes

(Re-)Load archetypes into %ARCH.

   }, sub {

}

=item load_tilecache

(Re-)Load %TILE and %FACE.
