This is a massive upgrade removing almost all pre-waf 1.6 script code. In addition, this does away with custom pkgconfig.py script for making .pc files and replaces it with waf's builtin mechanism. Massive thanks to Alex Afanasyev for ideas and bugfixing, to Alina Quereilhac for bugfixing and testing, and to Tom Henderson for thorough testing.

Waf 1.6
|
|
|
|
Try to detect if the project directory was relocated, and if it was,
|
|
change the node representing the project directory. Just call:
|
|
|
|
waf configure build
|
|
|
|
Note that if the project directory name changes, the signatures for the tasks using
|
|
files in that directory will change, causing a partial build.
