Welcome to the CLEO library (or simply CLEO) - a hugely popular extensible plugin for the Grand Theft Auto games series by Rockstar Games, allowing the use of thousands of unique mods which change or expand the gameplay. There are different versions of CLEO made for GTA III, GTA Vice City and GTA San Andreas. Using CLEO it's possible to add custom scripts written with Sanny Builder or another script editor to the game without starting a new game. Adding and removing a script is as easy as copying and deleting a file in the CLEO folder.
