Makefile

# This Makefile allows the app to be started and stopped easily.
#
# You need to follow these steps in README.md before starting the app for the first time.
#
# Usage:
#   make [rails-]fg       # start rails in the foreground normally
#   make halt             # shut down rails and its dependencies
#   make [up]             # start rails (in the background)
#   make [rails-]restart  # restart rails (in the background)
#   make [rails-]attach   # start rails in the foreground in a screen(1) session

# Settings:
# PROJ_ROOT := $(shell git rev-parse --show-toplevel)
