# Builds a Boost framework for the iPhone.
# 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 boost in Xcode
# less painful.
#
# To configure the script, define:
# BOOST_LIBS: which libraries to build
# IPHONE_SDKVERSION: iPhone SDK version (e.g. 8.0)
#
# Then go get the source tar.bz of the boost you want to build, shove it in the
# same directory as this script, and run "./boost.sh". Grab a cuppa. And voila.
