+# 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
