UMIL (Unified MOD Install Library) was built by EXreaction under the supervision of the MOD Team. This utility enables MOD Authors to create simple installation scripts for their MOD that allow the user to one-click install, update, or uninstall a Modification. Released under the GNU GPL license, UMIL is included within MOD Packages to make MOD Installations simple and automatic.
UMIL performs basic database actions that would be required to install a MOD. UMIL does not perform file edits. AutoMOD (Blinky) is the tool of choice for file edits and installing MODs from a MODX (xml) file. AutoMOD (Blinky) does not perform database changes, module, permission installations, etc. This is why UMIL exists.
