# Build script to automatically build Chocolate Doom. This will work
# on OSX and Linux, and hopefully Cygwin as well (havent tried)
#
# To build on OSX:
# 1. Install Xcode (available on your OSX DVDs or from the Apple
# website)
# 2. Type:
# curl http://www.chocolate-doom.org/build-chocolate-doom | sh
#
# To build on Linux:
# 1. Make sure gcc is installed (depends on your distribution).
# 2. Type:
# wget -O - http://www.chocolate-doom.org/build-chocolate-doom | sh
