+*** master-mode.el implements a minor mode for scrolling a slave
+buffer without leaving your current buffer, the master buffer.
+
+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.
