title: Start TeamCity Build via REST Call
body: <p>A little background.  </p>
  
  <p>In my environment we have a large number small .NET solutions each in their own Subversion repositories (500+).  We not a TFS shop and are currently evaluating moving our home grown CI process to TeamCity.  </p>
  
  <p>Instead of having these 500+ repos polling our Subversion server every 5-10 minutes or so I'd like to kick off a Project build via a post-commit-hook REST http call (as our current solution does).  I would then want TeamCity to update from SVN and commence the build process.  Is this possible?</p>
  
  <p>I see TeamCity has a REST API, just that the documentation is sparse.  I'm not sure how this example ties to anything I've got configured.  What is bt7?  How does it tie to the projects I've configured?</p>
