# Descrption: Basic SteamCMD app management using a clever CSV file.
#   Script accepts a single argument that filters the app list.
#   CSV file values: APP_ID, APP_NAME, APP_START_CMD.
#     APP_ID: The steam app id
#     APP_NAME: Human friendly name, used for display purposes only
#     APP_START_CMD: The command to start the app server assuming the CWD
#       is set to Steam's common app dir (.../Steam/steamapps/common/)
