title: Jenkins: trigger only on selected SVN Revisions
body: <p>We try to setup <strong>Jenkins</strong> with <strong>SVN</strong> repository (<strong>TortoiseSVN</strong>). We are new to Jenkins while we use SVN extensively.</p>
  <p>Our code is continuously committed to SVN. There is no need to trigger Jenkins on every revision.</p>
  <p>Is it possible to <strong>trigger Jenkins only if SVN revision is specially marked</strong> for triggering? For example, can Jenkins be triggered only if revision is tagged?</p>
