LMPC is the name of the complete package and the name of the biggest parts in it: The Little Movie Processing Centre.
LMPC is a collection of utilities to handle old (<=1.4) and new DOOM, DOOM ][, HERETIC, HEXEN and STRIFE LMP files. There is support for Duke Nukem 3D and Redneck Rampage DMO files, Quake DEM files, QuakeWorld QWD files and Quake II DM2 files (client recorded, server recorded, and relay files) too. For relay files, read the home page of the Quake II Relay project by Conor Davis ( cedavis@planetquake.com) http://www.planetquake.com/relay/
You can download the package from my Demo Specs page.
It is based upon the information in the Unofficial LMP format description, the Unofficial DMO format description, the Unofficial DEM format description, the Unofficial QWD format description and the Unofficial DM2 format description.
Read the apropriate document to find out the exact version numbers supported by LMPC. I write the format description and the program at the same time; so if it is described in the specs document, it is in general supported by the LMPC program.
