Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv30786
Added Files:
	test_os.py 
Log Message:
Start of a test suite for the "os" module -- this only tests the temporary
file management functions that have just been made available on more 
platforms.
--- NEW FILE: test_os.py ---
# As a test suite for the os module, this is woefully inadequate, but this
# does add tests for a few functions which have been determined to be more
# more portable than they had been thought to be.
