# This is a shell script that allows you to watch the CrossFit games from
# games.crossfit.com within the US, instead of being routed through ESPN3.
# It just fakes the Javascript library called by the stream to respond that
# you are outside of the US, and will clean up after itself once you're
# done.
#
# Requirements: root privileges (mucking around in /etc and running a server
# on port 80), Python >= 2.6 (may work with any 2.x but I'm not sure).
#
# It was written on an OS X machine: if you name it .command instead of
# .sh and mark it executable, you can actually just double-click the script
# in Finder to run it. On non-BSD-based systems, I don't remember if the
# hosts file is the same, so adjust as needed.
