18/**
19 * @fileoverview
20 * Registers a language handler for TCL
21 *
22 *
23 * To use, include prettify.js and this file in your HTML page.
24 * Then put your code in an HTML tag like
25 *      <pre class="prettyprint lang-tcl">proc foo {} {puts bar}</pre>
26 *
27 * I copy-pasted lang-lisp.js, so this is probably not 100% accurate.
28 * I used http://wiki.tcl.tk/1019 for the keywords, but tried to only
29 * include as keywords that had more impact on the program flow
30 * rather than providing convenience. For example, I included 'if'
31 * since that provides branching, but left off 'open' since that is more
32 * like a proc. Add more if it makes sense.
