;;
;; Usage:
;;
-;; Type `M-x ggtags-mode' to enable the minor mode, or as usual enable
-;; it in your desired major mode hooks. When the mode is on the symbol
-;; at point is underlined if it is a valid (definition) tag.
+;; `ggtags' is similar to the standard `etags' package. These keys
+;; `M-.', `M-,', `M-*' and `C-M-.' should work as expected in
+;; `ggtags-mode'. See the README in https://github.com/leoliu/ggtags
+;; for more details.
;;
-;; `M-.' finds definition or references according to the context at
-;; point, i.e. if point is at a definition tag find references and
-;; vice versa. `M-]' finds references.
-;;
-;; If multiple matches are found, navigation mode is entered, the
-;; mode-line lighter changed, and a navigation menu-bar entry
-;; presented. In this mode, `M-n' and `M-p' moves to next and previous
-;; match, `M-}' and `M-{' to next and previous file respectively.
-;; `M-o' toggles between full and abbreviated displays of file names
-;; in the auxiliary popup window. When you locate the right match,
-;; press RET to finish which hides the auxiliary window and exits
-;; navigation mode. You can continue the search using `M-,'. To abort
-;; the search press `M-*'.
-;;
-;; Normally after a few searches a dozen buffers are created visiting
-;; files tracked by GNU Global. `C-c M-k' helps clean them up.
+;; All commands are available from the `Ggtags' menu in `ggtags-mode'.
+
+;;; NEWS 0.8.10 (2015-06-12):
+
+;; - Tags update on save is configurable by `ggtags-update-on-save'.
+;; - New command `ggtags-explain-tags' to explain how each file is
+;; indexed in current project.
+;; - New user option `ggtags-sort-by-nearness' that sorts matched tags
+;; by nearness to current directory.
;;
-;; Check the menu-bar entry `Ggtags' for other useful commands.
+;; See full NEWS on https://github.com/leoliu/ggtags#news
