(The code used in tabnanny.py to process files and recursively directories fronm sys.argv is replicated a thousand times in various scripts of mine -- Tim took it from my now-defunct takpolice.py.

Those of you who have seen the compiler-sig should know that Jeremy made an improvement which will find its way into p2c. It's currently on display in the Python CVS tree in the nondist branch: see http://www.python.org/pipermail/compiler-sig/2000-February/000011.html and the ensuing thread for more details. --Guido van Rossum (home page: http://www.python.org/~guido/)
