  15 This manual is for `sketch', version 0.2 (build 161),
  16 Tuesday, September 08, 2009, a program that converts descriptions of simple
  17 three-dimensional scenes into static drawings. This version generates
  18 `PSTricks' or `PGF/TikZ' code suitable for use with the
  19 TeX document processing system.

  57
  58 <p><a name="index-keywords-171"></a>The keywords of <code>sketch</code> are <code>picturebox</code> <code>curve</code>
  59 <code>def</code> <code>dots</code> <code>frame</code> <code>global</code> <code>input</code>
  60 <code>line</code> <code>polygon</code> <code>put</code> <code>repeat</code> <code>set</code>
  61 <code>sweep</code> and <code>then</code>.  The <code>sketch</code> parser will note a
  62 syntax error if any of these are used in place of a proper identifier.
  63
  64    <p>In addition, there are reserved words
  65 <a name="index-reserved-words-172"></a>that can currently be defined by the user, but with the risk that
  66 future versions of <code>sketch</code> will reject those definitions.  The
  67 reserved words are <code>atan2</code> <code>cos</code> <code>inverse</code>
  68 <code>perspective</code> <code>project</code> <code>rotate</code> <code>scale</code>
  69 <code>sin</code> <code>special</code> <code>sqrt</code> <code>translate</code> <code>unit</code> and
  70 <code>view</code>.
