Well, ignoring Python packaging conventions isn't reasonable or
Pythonic either, but oh well.
Here's what you should do: Create ONE script that is a single entry
point to the everything. The script would accept a subcommand, set up
the Python path, and invoke the appropirate Python module (NOT script)
corresponding to that subcommand, say by calling a main() function
you've defined within.
Users would invoke the appropirate tool using the appropriate
subcommand (similar to tools like Subversion and GIT).
If you really can't use subcommands, make symlinks to the ONE script,
and have the ONE script check what name it was invoked with.
Notice the key idea in all of this: ONE script. When you design it
that a file can be used either as a script or as a module, you are
asking for trouble.
