Presets
From GMod Wiki
Presets are sets of Stool values/settings that can be put into a database. They can be very useful for complicated choosing. Wired Sound Emitter or Stacker rotations.
Presets are saved automaticly in garrysmod/settings/presets in the format generated by util.TableToKeyValues or util.KeyValuesToTable, therefor they can be read using these functions.
