+# LLVM does not provide ABI stability between different versions. For this
+# reason OE makes it possible to build and install different llvm versions
+# at the same time.
+#
+# This is true for the normal recipes as well as the native ones.
+#
+# All regular installation directories are prefixed with 'llvm${LLVM_RELEASE}'
+# e.g. "${STAGING_BINDIR}/llvm2.5" or "${STAGING_INCDIR}/llvm2.5"
+#
+# For your program or library that makes use of llvm you do should not need to
+# modify anything as long as it uses the results of various llvm-config
+# invocations. If you need customizations something is wrong and it needs to be
+# fixed (report bug).
+#
+# However the *recipe* for your program/library *must* declare
+# export WANT_LLVM_RELEASE = "<valid version number>"
+# The version number is picked up by a generic wrapper script which just calls
+# the variant of the specified version.
