DEF

DEF files, with the .def extension, are definition files for Doom 3. They are used to define, in plain ASCII, names for reusable assets that share a common set of properties.

Common definitions in Doom 3 include:
 * addondef
 * af
 * audio
 * email
 * entitydef
 * export
 * fx
 * mapdef
 * material
 * modeldef
 * particle
 * skin
 * sound
 * table
 * pda
 * video

Example
This is an abridged (incomplete) version of the def file for the tentacle commando. It is not functional as-is since many lines were removed, and only intended to illustrate the syntax.
