USAGE:
BeamMP-Server [arguments]
ARGUMENTS:
--help
Displays this help and exits.
--config=/path/to/ServerConfig.toml
Absolute or relative path to the
Server Config file, including the
filename. For paths and filenames with
spaces, put quotes around the path.
--working-directory=/path/to/folder
Sets the working directory of the Server.
All paths are considered relative to this,
including the path given in --config.
--version
Prints version info and exits.
EXAMPLES:
BeamMP-Server --config=../MyWestCoastServerConfig.toml
Runs the BeamMP-Server and uses the server config file
which is one directory above it and is named
'MyWestCoastServerConfig.toml'.
