-
-;;; Commentary:
-
-;; To enable the Go guru in Emacs, use this command to download,
-;; build, and install the tool in $GOROOT/bin:
-;;
-;;     $ go get golang.org/x/tools/cmd/guru
-;;
-;; Verify that the tool is on your $PATH:
-;;
-;;     $ guru -help
-;;     Go source code guru.
-;;     Usage: guru [flags] <mode> <position>
-;;     ...
-;;
-;; Then copy this file to a directory on your `load-path',
-;; and add this to your ~/.emacs:
-;;
-;;     (require 'go-guru)
-;;
-;; Inside a buffer of Go source code, select an expression of
-;; interest, and type `C-c C-o d' (for "describe") or run one of the
-;; other go-guru-xxx commands.  If you use `menu-bar-mode', these
-;; commands are available from the Guru menu.
-;;
-;; To enable identifier highlighting mode in a Go source buffer, use:
-;;
-;;     (go-guru-hl-identifier-mode)
-;;
-;; To enable it automatically in all Go source buffers,
-;; add this to your ~/.emacs:
-;;
-;;     (add-hook 'go-mode-hook #'go-guru-hl-identifier-mode)
-;;
-;; See http://golang.org/s/using-guru for more information about guru.
