Also I'd like to discuss what seems to me a common misconception in python packaging -- specifically, the use of cp -r source source-py2 and building both separately.
Best I can tell, this is primarily motivated by fear of py2/py3 specific bytecode being generated, but the thing is, this bytecode is all generated during package() inside of "$pkgdir" during the install step. You can check the contents of the build/ directory... it just copies the .py files and builds any ext_modules.
The main reason behind this (or why I started doing this) was sometimes the tests run inside the sources tree made both versions' .pyc files into the tree itself, and finally end up in the package. I had this problem for several times and end up having the separated build directories as template for new packages. This seems not the case for most packages now, so I agree that it should be avoided. -- Regards, Felix Yan
