ENV SUMMARY="Platform for building and running Ruby $RUBY_VERSION applications" \
    DESCRIPTION="Ruby $RUBY_VERSION available as docker container is a base platform for \
building and running various Ruby $RUBY_VERSION applications and frameworks. \
Ruby is the interpreted scripting language for quick and easy object-oriented programming. \
It has many features to process text files and to do system management tasks (as in Perl). \
It is simple, straight-forward, and extensible."
