One comment on this patch, for either Rene or Thomas (whoever wrote the code
in question).

Why blow up if trying to build a script-ful distribution for Windows
under (say) Unix?  Yeah, sure, we'll be doing unnecessary work in setting
the #! line to point to /usr/bin/python (or whatever), but I don't
see any Windows-specific code in build_scripts.py.

Please, no newlines in exception messages: however you handle this is a
crock, but the crock used throughout the Distutils is to assume that
someday, some clever tool will nicely reformat those run-on exception
messages.

Also, the "***" doesn't add anything: the fact that the script blows up with
an error message should be attention-getting enough.

OK, I'll check it in without the ban on script-ful distributions, and with
the exception-raising code rewritten.
