# Guidelines:
# - Providing applications written in OCaml is the main goal of our packaging.
# - Applications written in OCaml are static binaries.
# - A concept of shared libraries does not exist, beside the Dynlink module
# - All binaries go into the main package, in case they are produced.
# - All modules go into the -devel subpackage
# - Helper applications below /usr/lib/ocaml go into the -devel subpackage
# - License files go into the main package.
# - To aid debugging of cmxs files, their debuginfo is preserved by removing the executable bit.
# 
# get rid of /usr/lib/rpm/find-debuginfo.sh
# strip kills the bytecode part of ELF binaries
#
# provide empty _find_debuginfo_dwz_opts
# the .dwz files contains identical contents, which leads to identical
# checksums, which leads to file conflicts due to identical symlinks
