almost. my package has an if "sys.platform" .. and imports the 
platform implementation from an other file.

however, as Roger also pointed out, it's the module finder that just 
catches all imports. but well, it's maybe a bit inapropriate to follow up 
on Thomas' post he sure knows how py2exe works ;-)

yes. maybe i should put that in the docs... ok, done, i also added a for py2exe in the pyserial examples (CVS on

and the funny part is that Grant now packages a third party module that 
contains code from him (with his name in the sources of course, in the 
posix implementation)
