+# These packages are meant to be used for compiling packages that haven't been
+# ported to LLVM 3.6 yet. Such packages may depend on llvm35-libs but not on
+# llvm35 or clang35 which aren't co-installable with the LLVM 3.6 packages.
+
+# AG Fri Apr 6 07:18:08 CEST 2018: Resurrected from extra from which it
+# recently got kicked, with the following changes:
+
+# - couldn't get compiler-rt to compile any more, disabled for now
+
+# - include the host target only, to speed up compilation; if you need the
+#   cross compilation targets, change the configure option in the build
+#   function to --enable-targets=all
+
+# Please note that this is a split package, thus you need to install this with
+# an AUR helper such as aurman which supports that kind of thing, or download
+# the PKGBUILD and install manually using makepkg.
