Free psdoom software for linux

psDooM project is a process monitor and manager for *nix systems.
It could be considered a graphical interface to the ps, renice, and kill commands. psDooM is based on XDoom, which is based on id Softwares Doom.
This project started out as a proof-of-concept program for the web page "Doom as a tool for system administration" at http://www.cs.unm.edu/~dlchao/flake/doom by Dennis Chao at the University of New Mexico.
Dennis took the GPLd sources of XDoom and added code so that processes running on the system would be instantiated as monsters, and wounding and killing them corresponds to renicing and killing the processes.
Enhancements:
- Changed shell scripts in contrib dir to shorten command length when displayed with ps.
- Use ~/.psdoom rather than ~/.xdoom for savegames, config files, etc.
- Users need to copy current .doomrc and .xdlaunchrc files to ~/.psdoom.
- Added references to psDooM in startup header text, X resources, and window title bar.
- Modified xdlaunch (ps-xdlaunch) to run ps-xdoom.
- Added ability to pass psDooM-specific command line flags to ps-xdoom through ps-xdlaunch.
