# Maintainer notes:
# - This ebuild uses Bundler to download and install all gems in deployment mode
# (i.e. into isolated directory inside application). That's not Gentoo way how
# it should be done, but GitLab has too many dependencies that it will be too
# difficult to maintain them via ebuilds.
