title: "svn is not recognized" error in PowerShell
body: <p>I'm trying to reach SVN from Windows PowerShell but I can't. For example, if I type <code>svn help</code> I get:</p>
  
  <blockquote>
    <p>svn : The term 'svn' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.</p>
  </blockquote>
  
  <p>I have TortoiseSVN installed on the computer which should to my knowledge should allow me to use <code>svn</code> commands.</p>
  
  <p>I also have the same problem when I try to use Gource.</p>
