[Scons-users] Changing working directory

[Kenny, Jason L]

I remember a few years ago I had made a similar argument that the a cd <directory> should be added to the command line actions with a chdir was added to the builder. I believe this is a good improvements. I don't recall why this was not done. I believe it was something that SCons should fix some code that handles loading a sconstruct/sconscript to have it not change directories at all. ( as it currently will try to change the directory to the source area or build variant area depending on if the build variant directory exists or not). 

In short however I am for such as change. I know I have to for some of the work I do in Parts or for my local product builds, so a similar "cd <some directory>" to allow it to work correct and with -J based builds. Have a more formal hook would be nice.

Maybe it could be good point to provide something like '$CDCOM' 
construction variable by default? Initially it could be defined in a way similar to what the 'tex' tool does:
