# Reasons for installing packages
# - less: better pager, for Pry in particular, but not only
# - nodejs: assets compilation
# - npm: yarn
# - postgresql-client-11: rails dbconsole
# - vim: rails secrets:edit, rails credentials:edit, bundle open, etc.
# - xauth and xvfb: headless browser testing
# - yarn: webpacker
