cpython/Lib/distutils/command/build.py
Greg Ward 3459381e2a Changed so all the help-generating functions are defined, at module-level,
in the module of the command classes that have command-specific
help options.  This lets us keep the principle of lazily importing
the ccompiler module, and also gets away from defining non-methods
at class level.
