[Tutor] hardware specs from python on OSX

[Yi Qiang]

Hi,
I am trying to get some basic information about the computer's
hardware specs in OSX in python.  In linux I can get most of what I
need from the /proc filesystem.  Is there an equivalent in OSX?  If
not, where else can I get information about the system from?  I need
CPU model, # of cpus, cpu speed, physical memory, etc.

Thanks,
Yi
