Automatically launch freedoom with an engine
freedoom2 [-p PORT|--] [ARGS]
Freedoom is a project to create a complete free-content game based on the Doom engine (often called “source ports” or simply “ports”), which itself is free software. In addition, it maintains compatibility with Doom itself and is capable of playing the wide variety of modifications (“mods”) that have been released by an active community since 1993.
This command is a simple shell script to assist in running Freedoom, which is not a game engine itself nor part of any engine project, but playing Freedoom should remain simple. Only accepted as the first argument, you may pass -p PORT, which will run Freedoom using the PORT specified. As an alternative, you may make a symbolic link named $HOME/.doomport to your preferred port. A port specified on the command line explicitly overrides $HOME/.doomport, whereas the existence of the symbolic link will override the detection of port based on a hard-coded list.
Additional arguments passed to the program, or after specifying -- as the first option, will be passed to the engine being called. This can allow you to use options such as -file to load mods or anything else available with the engine of choice.
