# NOTE: 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.
