Python wrappers for pw (freebsd password tool)

[VanL]

Hello,

Has anyone written a python wrapper for pw*?  Whether by swig, popen, or 
os.system it doesn't matter.  I need one, and would rather reuse 
existing code than write from scratch.

Alternatively, does anyone have any utilities for updating the freebsd 
password database file?  I know about pwd in the statndard library, but 
that is a read-only tool.  I want to programmatically add users, not 
just read the file.

* I am referring specifically to pw for freebsd, the swiss-army-knife 
password database manipulation tool.

Thanks,

VanL
