[Fred L. Drake]

Update of /cvsroot/python/python/dist/src/Doc/lib
In directory slayer.i.sourceforge.net:/tmp/cvs-serv3365/lib

Modified Files:
	libos.tex 
Log Message:

Added \versionchanged comment to os.popen() noting that it was unreliable
in earlier versions of Python; this is useful information for people
interested in writing code that is portable across Python versions.

Suggested by Peter Funk <pf@artcom-gmbh.de>.
