[Scons-users] how to configure scons for Visual Studio 2017 (RC)

[Thomas Berg]

Ah, I misunderstood, for a moment I thought win32com was part of vanilla
python and didn't require anyithing else, but of course I already had
pywin32 installed.

The javascript alternative has the advantage that it doesn't require the
user to install anything, we can just launch a cscript.exe command (which
is available in Windows) running a simple script, and we can parse the
output from python. Do you have any good reasons for not trying this path?
Not needing pywin32 seems very attractive to me.

Not sure if a ctypes solution is any easier, or if it's doable at all.
