DominionLib

DominionLib is a faithful fork of McHorse's McLib with the goal of providing a more stable base for Changeling, as well as backport McLib features to older Minecraft versions that Changeling uses.

It has many of the same features, such as a GUI library, networking, and a math expression parser.

If you are using Changeling, you should switch from McLib to DominionLib to ensure smooth updates.

Announcements related to DominionLib and other mods I maintain will be mentioned in the Minecraft Forum thread.
