;; "What am I looking at?"
;;
;; This module helps you answer that question. It helps you look up whatever
;; you're looking at, with:
;;
;; 1. A dwim Jump-to-definition functionality that "just works", with the help
;;    of `dumb-jump' and `xref'.
;; 2. A dwim interface to the new (and experimental) xref API built into Emacs.
;;    Once its API is more stable, backends could be written (or provided by
;;    plugins) to create universal find-references and find-definition
;;    functionality. Warning: xref may change drastically in future updates.
;; 3. Simple ways to look up the symbol at point in external resources, like
;;    stackoverflow, devdocs.io or google. See `+jump/online' (TODO Test me!)
;; 4. TODO Automatic & transparent integration with cscope dbs + ctags.
;;    Databases are optionally isolated to the Emacs environment.
