;;; Commentary:

;; `master-mode' is a minor mode which enables you to scroll another
;; buffer (the slave) without leaving your current buffer (the master).

;; It can be used by sql.el, for example: The SQL buffer is the master
;; and its SQLi buffer is the slave.  This allows you to scroll the SQLi
;; buffer containing the output from the SQL buffer containing the
;; commands.
;;
;; This is how to use sql.el and master.el together: The variable
;; sql-buffer contains the slave buffer.  It is a local variable in the
;; SQL buffer.
