# Module Name: fcgi.py
#
# Description: Handles communication with the FastCGI module of the
# web server without using the FastCGI developers kit, but
# will also work in a non-FastCGI environment, (straight CGI.)
# This module was originally fetched from someplace on the
# Net (I don't remember where and I can't find it now...) and
# has been significantly modified to fix several bugs, be more
# readable, more robust at handling large CGI data and return
# document sizes, and also to fit the model that we had previously
# used for FastCGI.
#
# WARNING: If you don't know what you are doing, don't tinker with this
# module!
