;;; Commentary:
;;
;; Semantic is a package that provides a framework for writing
;; parsers. Parsing is a process of analyzing source code based on
;; programming language syntax. This package relies on Semantic for
;; analyzing source code and uses its results to perform smart code
;; refactoring that based on code structure of the analyzed language,
;; instead of plain text structure.
;;
;; This package provides the following features for Emacs Lisp:
;;
;; - `srefactor-lisp-format-buffer': Format whole buffer.
;; - `srefactor-lisp-format-defun': Format the current defun point is in.
;; - `srefactor-lisp-one-line': Transform all sub-sexpressions current sexpression at
;; point into one line separated each one by a space.
;;
;; - `srefactor-lisp-format-sexp': Transform all sub-sexpressions current sexpression
;; at point into multiple lines separated. If the head symbol belongs to the
;; list `srefactor-lisp-symbol-to-skip', then the first N next symbol/sexpressions
;; (where N is the nummber associated with the head symbol as stated in the
;;  list) are skipped before a newline is inserted.
