###
#   SimulationCraft docker image
#
#   Available build-arg:
#     - THREADS=[int] Default 1, provide a value for -j
#     - NONETWORKING=[0|1] Default 0, 0 - armory can be used if an api-key is provided, 1 - no import capabilities
#
#   Example usage:
#   - creating the image (note the dot!)
#   docker build --build-arg THREADS=2 --build-arg NONETWORKING=1 -t simulationcraft .
#                                    ^ your intended thread count to optimize simc for
#                                                                    ^ name of the image
#   - run the image
#   docker run simulationcraft ./simc spell_query=spell.name=frost_shock
#                              ^ start of the command
#
#   To reduce the footprint of this image all SimulationCraft files are
#   removed except for the following files and directories (including
#   their files)
#   - ./simc
#   - ./profiles/*
