[Scons-users] Debugging SCons files as Python scripts

[Tony Whitley]

Thanks, I didn't know about that.  It would do what I need although our
whole build takes a couple of minutes before it gets round to our SCons
files which makes my test harness more agile.  Though maybe I could simply
make my own "parent" sconscript that calls our files and run that.
