    # 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. 5.1)
    #
    # 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.

    # The EXTRA_CPPFLAGS definition works around a thread race issue in
    # shared_ptr. I encountered this historically and have not verified that
    # the fix is no longer required. Without using the posix thread primitives
    # an invalid compare-and-swap ARM instruction (non-thread-safe) was used for the
    # shared_ptr use count causing nasty and subtle bugs.
    #
    # Should perhaps also consider/use instead: -BOOST_SP_USE_PTHREADS
