5# DESCRIPTION
6# Factory module for constructing templates from Perl code.
7#
8# AUTHOR
9# Andy Wardley <abw@wardley.org>
10#
11# WARNING
12# Much of this module is hairy, even furry in places. It needs
13# a lot of tidying up and may even be moved into a different place
14# altogether. The generator code is often inefficient, particulary in
15# being very anal about pretty-printing the Perl code all neatly, but
16# at the moment, that's still high priority for the sake of easier
17# debugging.
18#

23# modify it under the same terms as Perl itself.
