For me, too.

I'd second this. I'd rather have a more intelligent cminstall,
which tries to figure out all the information for itself, and then
presents the user with a standard setup and directions how to
solve any remaining problems. And this way we don't have to bother
with more more scripting languages, too.

This would be another approach to making things simpler. We can
try both ways at once, though.

I wouldn't like to remove any flexibility there is, as in my
experience, it will be needed once it has been removed. Perhaps
I'll have a try at making cminstall better during the next weeks.
The main problem with installation issues is, that one needs access
to all relevant target platforms to check things and test them, and
that it takes much time to do this ;-)
