# When building from scratch:
#   docker build -t rperl-image .
#   docker run --name rperl_instance -ti rperl-image
# After this has been loaded onto the Docker Hub, a much faster command will be available.

# These packages are prerequisites for RPerl or Pluto.
# Packages named `lib*-perl` are CPAN modules, which install more cleanly
# (and quickly) as packages than via `cpanm`.
