[Distutils] Installing scripts

Tim just pointed this thread out to me, so I thought I would try and keep it

How about something like:

strip_extensions = {"posix": "txt py pyw", "darwin": "txt" }

Where strip_extensions is a dictionary, keyed by the platform name (either
sys.platform or os.name - whatever makes sense.  The value is the list of
extensions that should be stripped.

This allows README.FIRST etc to remain intact, and allows fine control over
what platforms it is applied to.

The downside is that it can't really be spelt on the command-line.  However,
I argue that anyone who needs such fine grained control will have somewhere
more suitable to specify it anyway.

Would that make sense?

Mark.
