[Scons-users] --no-cache-dir

[Bill Deegan]

Bassem,

Indeed the scons packaging needs some work.
Pull requests are welcome.

The setup.py logic is ancient and hasn't been updated in a while.
(Excluding some changes to all building windows exe packages which we've
dropped with the 3.0.0 release)

It's on the list, but I'm focusing on some performance work at this time.
-Bill
