Non-math-geek needs help with CRCs (binascii.crc32)

That doesn't seem to mention anything about poly $EDB88320, which is the
code I'm trying to a) be compatible with, b) define for future developers so
they don't have to go through this whole mess.  It appears whatever Python
uses is compatible, but stating the poly by itself doesn't mean anything.

Somehow, depending on how the numbers are massaged, the old code based on
$EDB88320 is compatible with what the above site documents as $04C11DB7.

This is all very confusing..
