Minecraft Forge (API) for Minecraft 1.7.2 with installer is an open-source tool or a modification layer which provides modding capabilities to developers and players. It allows them to remove and sometimes minimize the incompatibilities between Minecraft mods. For instance; players can install multiple mods of similar functionality without any glitches or errors. On the other hand developers can hook their mods rightly without worrying about conflicts with other mods.
