Sorry for not responding. Since setup.exe support is a team effort
these days, I assume that everyone thought that everyone else would
respond.
I don't think that there is anything in contrib.html which suggests that
you will get instant responses to questions. Small consolation, I know.
I know that I didn't respond because of a few things: 1) You said that
the patch was untested, and I didn't have time to test it, 2) Your patch
didn't adhere to the guidelines on contrib.html, 3) Your patch did not
seem to be against the current sources, which would potentially mean
that there would be a lot of effort getting it into the current sources.
So, I probably should have just responded and mentioned all of this. I
did have your email in my queue of things to respond to. I'm sorry that
I (or some other developer) didn't respond sooner.
This kind of functionality has always been something that we've been
interested in adding to setup.exe. I've Cc'ed cygwin-developers with
this message in the hopes that it will generate a discussion on how
to proceed with this kind of functionality.
