-Last update 15 June 2014
-
-This is a compiler frontend for the Go programming language
-(http://golang.org/).  The frontend was originally developed at
-Google, and was released in November 2009.  It was originally written
-by Ian Lance Taylor <iant@golang.org>.
-
-It was originally written for GCC (http://gcc.gnu.org/).  As of this
-writing it only supports GCC, but the GCC support has been separated
-from the rest of the frontend, so supporting another compiler is
-feasible.
-
-The go subdirectory holds the frontend source code.  This is mirrored
-to the gcc/go subdirectory in the GCC repository.
-
-The libgo subdirectory holds the library source code.  This is a copy
-of the main Go library with various changes appropriate for this
-compiler.  The main Go library is hosted at
-http://go.googlesource.com/go, in the src directory.  The libgo
-subdirectory is mirrored to the libgo subdirectory in the gcc
-repository.
