[Scons-dev] API for warnings and debug messages

[William Deegan]

Gary,

Would it be smart to use the python logging module? (it’s in 2.7 and 3.x)
https://docs.python.org/2/library/logging.html

Less code = good?

Funny you should mention it; I have a patch pending to add an internal  
tracing facility to SCons just for this kind of thing. The current  
tracing code is ad hoc. I wrote my new version when Dirk and I were  
debugging that node caching problem a few months ago as a  
generalization of (and replacement for) --taskmastertrace. I will try  
to put together a pull request very shortly. It's only a start but  
hopefully will be useful.
