+     "GNU GLOBAL is a source code tagging system that works the same way
+across diverse environments (Emacs, vi, less, Bash, web browser, etc).
+You can locate specified objects in source files and move there easily.
+It is useful for hacking a large project containing many
+subdirectories, many #ifdef and many main() functions.  It is similar
+to ctags or etags but is different from them at the point of
+independence of any editor.  It runs on a UNIX (POSIX) compatible
+operating system like GNU and BSD.")
