+" ==============================================================================
+" History: This was originally part of auctex.vim by Carl Mueller.
+"          Srinath Avadhanula incorporated it into latex-suite with
+"          significant modifications.
+"          Parts of this file may be copyrighted by others as noted.
+" CVS: $Id: brackets.vim 997 2006-03-20 09:45:45Z srinathava $
+" Description:
+" 	This ftplugin provides the following maps:
+" . <M-b> encloses the previous character in \mathbf{}
+" . <M-c> is polymorphic as follows:
+"     Insert mode:
+"     1. If the previous character is a letter or number, then capitalize it and
+"        enclose it in \mathcal{}
+"     2. otherwise insert \cite{}
+"     Visual Mode:
+"     1. Enclose selection in \mathcal{}
+" . <M-l> is also polymorphic as follows:
+"     If the character before typing <M-l> is one of '([{|<q', then do the
+"     following:
+"       1. (<M-l>       \left(\right
+"               similarly for [, |
+"          {<M-l>       \left\{\right\}
+"       2. <<M-l>       \langle\rangle
+"       3. q<M-l>       \lefteqn{}
+"     otherwise insert  \label{}
+" . <M-i> inserts \item commands at the current cursor location depending on
+"       the surrounding environment. For example, inside itemize, it will
+"       insert a simple \item, but within a description, it will insert
+"       \item[<+label+>] etc.
+" 
+" These functions make it extremeley easy to do all the \left \right stuff in
+" latex.
+" ==============================================================================
