# MEMO:
#    For each OS X version, create bottles with:
#
#    `brew uninstall mulle-objc/software/mulle-clang-project`
#    `brew install --formula --build-bottle mulle-clang-project.rb`
# Now it gets retarded:
#    `brew tap-new mulle-objc/software`
#    `cp mulle-clang-project.rb /usr/local/Homebrew/Library/Taps/mulle-objc/homebrew-software/Formula/`
#    `brew bottle mulle-objc/software/mulle-clang-project`

#
#     scp -i ~/.ssh/id_rsa_hetzner_pw \
