This patch was developed primarily to reduce the size of the
  frozen binary.  It is particularly useful when freezing for 'small'
  platforms, such as Palm OS, where you really want to save that
  last miserable byte.

  A limitation of this patch is that it does not provide any feedback
  about the replacements being made.  As the path matching
  is case-sensitive this may lead to unexpected behaviour for DOS
  and Windows people, eg
      > freeze.py -r C:\Python\Lib\=py\ goats.py
  should probably be:
      > freeze.py -r c:\python\lib\=py\ goats.py
