  /**
   * @fileoverview
   * Registers a language handler for TCL
   *
   *
   * To use, include prettify.js and this file in your HTML page.
   * Then put your code in an HTML tag like
   *      <pre class="prettyprint lang-tcl">proc foo {} {puts bar}</pre>
   *
   * I copy-pasted lang-lisp.js, so this is probably not 100% accurate.
   * I used http://wiki.tcl.tk/1019 for the keywords, but tried to only
   * include as keywords that had more impact on the program flow
   * rather than providing convenience. For example, I included 'if'
   * since that provides branching, but left off 'open' since that is more
   * like a proc. Add more if it makes sense.
