+%description
+LLVM is a compiler infrastructure designed for compile-time, link-time, runtime,
+and idle-time optimization of programs from arbitrary programming languages.
+LLVM is written in C++ and has been developed since 2000 at the University of
+Illinois and Apple. It currently supports compilation of C and C++ programs, 
+using front-ends derived from GCC 4.0.1. A new front-end for the C family of
+languages is in development. The compiler infrastructure
+includes mirror sets of programming tools as well as libraries with equivalent
+functionality.
