Synopsis
  A licensor or a licensee wants to check whether a digitally embedded
  Creative Commons license associated with a file (a Web site in
  particular) is valid, does not use deprecated means to express it,
  and matches what the user has been expecting. Therefore, one opens
  the Web site and either pastes the source code as a direct input,
  uploads a file, or provides a link to retrieve it. The software
  displays the results of the analysis in a human-readable manner.
