dia templates

[Robert Wadley <rob robntina fastmail us>]

I am interested in contributing some artwork for use as a template. I
noticed that the images themselves are .png images (I can do that) but
that there are also other files (.shape) Where can I find information on
how to create this file? are these generated automatically by some
program or do you have to manually write the file? Are there any other
specific tools you use to create a template?
