Checked in with Andrew's blessing, I leave the comments with which
this was posted to distutils-sig in.
Here is what I've hacked together over some spare time
at the weekend. I would appreciate feedback, as I've told
before I'm neither a great author, nor native english speaker,
nor anything else.
Mostly I've completed (and written) docs for bdist_wininst
(where I'm an experert for), also I've started some stuff
for the data_files and scripts option.
Should I continue in this way? Would others like to jump in?
