With or without the -m switch, scripts installed by setuptools will 
find the version they are specified to use, without the user needing 
to do anything.  So, you can have a default version of an egg (used 
by the interpreter and non-setuptools scripts), and then some 
non-default versions that are used by scripts.

zc.buildout and virtualenv also have their own ways of accomplishing 
the same thing, e.g., by hardcoding paths in an installed script.
