Introduction
The Scrap Mechanic Content Compiler is a program found in the Scrap Mechanic Release folder.
"C:\Program Files (x86)\Steam\steamapps\common\Scrap Mechanic\Release\ContentCompiler.exe" on windows.
It is used by the mod tool to generate part icons for mods, but it can do a bit more than that!
