Update of /cvsroot/python/python/dist/src/Tools/scripts
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3865
Added Files:
hotshotmain.py
Log Message:
The bagpipe didn't say "no" (*), so here's a main program script useful for
running an application under hotshot's control. Only slightly embellished
from what Walter Dörwald posted to python-dev.
(*) http://www.icdc.com/~roadkill/silverstein/turtle.html
--- NEW FILE: hotshotmain.py ---
#!/usr/bin/env python
# -*- coding: iso-8859-1 -*-
