-The `pkg` and `exe` commands are for end-users and create a full standalone python package that can be installed locally using `make install` based on the auto-generated `Makefile`.  Theoretically these packages could be uploaded to https://pypi.org/ for wider distribution, but that would require a lot more work to handle all the different possible python versions and coordination with the Go source version, so it is much better to just do the local make install on your system.  The `gen` and `build` commands are used for testing and just generate / build the raw binding files only.

 IMPORTANT: many errors will be avoided by specifying the `-vm` option to gopy, with a full path if needed, or typically just `-vm=python3` to use python3 instead of version 2, which is often the default for the plain `python` command.
