# Run single command from Procfile
# This script is a basic replacement for foreman when running on Docker. When
# starting the docker instance, specify as command `script/start <type>`.
# `type` is looked up in `Procfile` and the command is started. This allows e.g.
# docker-compose to run multiple process/dyno types from a single image, without
# needing to know the exact command (which may change over time).

echo "Usage: $0 <process type>" 1>&2
echo "Note that some process types need the PORT environment variable."
