The manual explains the capabilities, syntax, and use of current GRASS 5.x modules. Sections contain entries which are ordered alphabetically by module name. Each entry contains:

Each entry may optionally include a description of the module's operation in interactive mode, and a discussion of "bugs," limitations, or special notes of interest.
