# mcrf-init.sh - Initialize a McRogueFace game project
#
# Creates a game project directory with symlinks to a pre-built engine,
# so game developers only write Python + assets, never rebuild the engine.
#
# Usage:
#   mcrf-init                  # initialize current directory
#   mcrf-init my-game          # create and initialize my-game/
#
# Setup (add to ~/.bashrc):
#   alias mcrf-init='/path/to/McRogueFace/mcrf-init.sh'
#   # or: export PATH="$PATH:/path/to/McRogueFace"
#
# After init:
#   make run                   # run the game
#   make dist                  # package for distribution
