Update of /cvsroot/python/python/dist/src/Lib/test/output
In directory usw-pr-cvs1:/tmp/cvs-serv20941/python/dist/src/Lib/test/output
Added Files:
test_difflib
Log Message:
Moved SequenceMatcher from ndiff into new std library module difflib.py.
Guido told me to do this <wink>.
Greatly expanded docstrings, and fleshed out with examples.
New std test.
Added new get_close_matches() function for ESR.
Needs docs, but LaTeXification of the module docstring is all it needs.
