While I'm still waiting for the money to come in, I have changed the
wise script (but this is still uncommitted) to fire up compileall.py
on the standard library, exluding the Lib/test subdir, in both normal
and optimized mode. This can be disabled in the advanced install
It fires up this ugly dos box, but I don't have time nor motivation to
write a wise extension only for a progress bar instead - the only other
possibility would be to run the compilation with pythonw.exe, and so
totally hide it from the user, and run it in the background without
waiting for it.
If I find time before my vacation, I can try to build an installer beta
and upload it to starship (hopefully this works again), if anyone wants
to try it out.
