GregMek

“This mod enables Mekanism’s chemical processing system to directly handle and refine GregTech ores.”

Why this fits:

• Direct: States the core function (“enables… to directly handle and refine”).

• Specific: Names both mods (“Mekanism”, “GregTech”) and the system involved (“chemical processing”).

• No Fluff: Omits marketing language, focusing purely on technical integration.

• Clear Scope: Explicitly links GT ores → Mek processing.

If even shorter is needed:
“Adds GregTech ore support to Mekanism’s chemical processing.”
