[Python-Dev] first pass at a release checker

[Anthony Baxter]

Here's the first hack at a quick script for checking a release
tarball for sanity. Please suggest additional checks to make.

At the moment it checks:
  tarball name
  tarball unpacks to a correctly named directory
  no CVS directories in the tarball
  no Release date: XXX in Misc/NEWS
  "configure ; make ; make test" works

Additional checks I plan to add at some point:
  check the version number in Include/patchlevel.h
  check the version number and build number in the windows-specific area

Where should something like this (cleaned up a bit) be checked in?
Tools/something?
