+    """The LLVM Project is a collection of modular and reusable compiler and
+       toolchain technologies. Despite its name, LLVM has little to do with
+       traditional virtual machines, though it does provide helpful libraries
+       that can be used to build them. The name "LLVM" itself is not an acronym;
+       it is the full name of the project.
