title: Drawing Sequence Diagrams
body: <p>I'm looking for an easy language/command line utility to draw <a href="http://ypso6q.blu.livefilestore.com/y1p-P2rkq2bo4evAZPMq3593a-W1zhXMm6Hzn9wBNCsOmlPRX0fuCx8XOMS-6gU5ifzRJe8VZ6afTTtFxMjTLCTeCfjYM3XzFwj/dotNETSequenceDiagram.jpeg" rel="noreferrer">sequence</a> and <a href="http://www.scienceprog.com/wp-content/uploads/TimingDia/image011.png" rel="noreferrer">timing</a> diagrams (could be 2 different tools). I've already found <a href="http://www.mcternan.me.uk/mscgen/" rel="noreferrer">Mscgen</a> for sequence diagram drawing and looks pretty good, but I'm studying other possibilities.</p>
  
  <p>Thanks</p>
