/**
* This is similar to the lang-tcl.js in JavaScript Prettify.
*
* All comments are adapted from the JavaScript Prettify.
*
* 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.
