;; API for providing the semantic content of a buffer.
;;
;; The Semantic API provides an interface to a series of different parser
;; implementations.  Each parser outputs a parse tree in a similar format
;; designed to handle typical functional and object oriented languages.
;;
;; To enable Semantic, turn on `semantic-mode', a global minor mode
;; (M-x semantic-mode RET, or "Source Code Parsers" from the Tools
;; menu).  To enable it at startup, put (semantic-mode 1) in your init
;; file.
