// -----------------------------------------------------------------------------
// Example Filterscript for the Area 51 (69) Base Objects
// ------------------------------------------------------
// By Matite in March 2015
//
//
// This script removes the existing GTASA Area 51 (69) land section, fence and
// buildings. It then replaces the land section and buildings with the new
// enterable versions. It also replaces the perimeter fence and adds two
// gates that can be opened or closed.
//
// Warning...
// This script uses a total of:
// * 11 objects = 1 for the replacement land object, 7 for the replacement
//   building objects, 1 for the outer fence and 2 for the gates
// * Enables the /a51 command to teleport the player to the Area 51 (69) Base
// * 2 3D Text Labels = 1 on each gate
