Apache::Throttle - Apache/Perl module for speed-based content negotiation

Apache::Throttle is a package designed to allow Apache webservers to
negotiate content based on the speed of the connection.

It's primary purpose is to transparently send smaller (lower
resolution/quality) images to users with slow internet connections,
but it can also be used for many other purposes.

Prerequisites:
  * Apache w/ mod_perl
  * IPC::Shareable
  * Time::HiRes and Image::Magick are also recommended.

Quick Start:
  1) "perl Makefile.PL"
