# Builds a Libpng framework for the iPhone and the iPhone Simulator. | |
# Creates a set of universal libraries that can be used on an iPhone and in the | |
# iPhone simulator. Then creates a pseudo-framework to make using libpng in Xcode | |
# less painful. | |
# | |
# To configure the script, define: | |
# IPHONE_SDKVERSION: iPhone SDK version (e.g. 8.1) | |
# | |
# Then go get the source tar.bz of the libpng you want to build, shove it in the | |
# same directory as this script, and run "./libpng.sh". Grab a cuppa. And voila. |
