I write these because I like to. Please enjoy as you see fit.

Questions to poly@omino.com, subject line should start with
"plugins" so my spam filter lets it in.

This file has been preprocessed to be
standalone.  I develop them against some
reusable libraries -- such as for dialog
layout -- but for distribution it's nicer to
have just one file. dvb 2007.
