runtime, and idle-time optimization of programs from arbitrary programming
languages.  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.")
