[Pythonmac-SIG] using the "PyUSB" module

[Rekow Warren]

I am a new MacPython (ver 2.6.1) user who has downloaded the "PyUSB"  
module, but am unclear about how to make it available for use in a  
program. Included among the downloaded files is 'setup.py' (and  
'setup.pyc'). Running 'setup.py' via IDLE yields the following error  
msg:
---
Traceback (most recent call last):
   File "/Applications/Python 2.6/pyusb-0.4.1/setup.py", line 62, in  
<module>
     ext_modules = [usbmodule])
   File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ 
python2.6/distutils/core.py", line 140, in setup
     raise SystemExit, gen_usage(dist.script_name) + "\nerror: %s" % msg
SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2  
[cmd2_opts] ...]
    or: setup.py --help [cmd1 cmd2 ...]
    or: setup.py --help-commands
    or: setup.py cmd --help

error: no commands supplied

It seemed that 'setup.py' should be run in order to access functions  
in the PyUSB module, but perhaps I misunderstand the process. It  
would be appreciated if someone could suggest a related reference to  
read.
Thanks, Warren
