+# NOTE: When bumping you need to adjust the *_VER strings in
+# src_install() to honour newer versions in the package (they
+# are maintained separately upstream).
+# As High Performance Erlang (HiPE) messes around a lot with
+# assembler, it breaks hardened and some normal systems, so it has
+# been disabled. Try with newer versions though.
+# If you need symlinks for binaries please tell maintainers or open up a bug
+# to let it be created.
+
+# erlang uses a really weird versioning scheme which caused quite a few problems
+# already. Thus we do a slight modification converting all letters to digits to
+# make it more sane (see e.g. #26420)
+
+# the next line selects the right source.
