+
+This is the runtime support library for the Go programming language.
+This library is intended for use with the Go frontend.
+
+The library has only been tested on GNU/Linux using glibc.  It should
+not be difficult to port to other operating systems.
+
+The library has only been tested on x86/x86_64 systems.  It should not
+be difficult to port to other architectures.
+
+Directories:
+
