This may be a stupid question, but what directory is considered the
“source” directory of python. I downloaded a tarball from python.org for
2.7.10, and it has numerous directories with source code. There is a
“Modules” directory, which probably refers to standard library code. There
is also a Python directory, which looks more like what I want...
