ptrace vs. python-ptrace

[Grant Edwards]

I'd like to do some experimentation with the Linux ptrace facility.
Before I jump in, I was wondering if anybody has any comments they'd
like to offer on the relative merits of ptrace vs. python-ptrace:

http://pypi.python.org/pypi/ptrace
http://pypi.python.org/pypi/python-ptrace

Ptrace appears to have been updated more recently that python-ptrace,
but python-ptrace includes some sample applications that probably get
me closer to my end-goal.

Are the APIs compatible (or at all similar)?
