inherit elisp-common eutils flag-o-matic multilib versionator
# 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). You even need to adjust the version number
# in the last comment.
# 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.
MY_PV="R$(get_major_version)B-$(get_version_component_range 3)"
# ATTN!! Take care when processing the C, etc version!
