    <abstract>
      The snapshot package helps the owner of a LaTeX document obtain
      a list of the external dependencies of the document, in a form
      that can be embedded at the top of the document. It provides a
      snapshot of the current processing context of the document,
      insofar as it can be determined from inside LaTeX.  If a
      document contains such a dependency list, then it becomes
      possible to arrange that the document be processed always with
      the same versions of everything, in order to ensure the same
      output. This could be useful for someone wanting to keep a LaTeX
      document on hand and consistently reproduce an identical DVI
      file from it, on the fly; or for someone wanting to shield a
      document during the final stages of its production cycle from
      unexpected side effects of routine upgrades to the TeX system.
