commandname [-flags] [parameters...]
All underscores in the command name are ignored:
acoolcommand call the same command.
If you want to find uses of a command in the game's script files, Arx Libertatis includes a helper script:
Script commands can accept an optional set of flags. Each flag is a single character and the order of the flags doesn't matter. Flags always come before all other parameters.
The number of parameters a command is fixed fixed for each set of flags.
