   V.E.R.A.'s license blurb releases it under GFDL version 1.1 or later, but the

 Carsten Leonhardt, Robert D. Hilliard, and Christoph Berg never declared the
 license under which their work fell. As of October 2013, the only remaining
 work from Carsten's maintainership is six short changelog entries. The work
 remaining from Robert's maintainership is:
  * the historic dict-vera changelog (debian/dict-vera.changelog-old)
  * his changelog entries in debian/changelog
  * the calls to dictdconfig and restarting dictd in debian/{postinst,postrm}
  * the calls to makeinfo and dictzip in debian/rules
  * the regexes to remove certain kinds of texinfo markup when generating the
    dictd file (debian/sedfile)
 All that remains from Christoph Berg's QA upload is his changelog entry and a
 call to dpkg-parsechangelog to debian/rules to determine the package's version.
 Since Robert, Carsten, and Christoph maintained or contributed to this package
 for Debian as Debian Developers after having agreed to abide by the DFSG, their
 works are implicitly distributable under a DFSG compliant license.
 .
 Subsequent contributors agreed to distribute their contribution to the package
 under the GFDL-1.1+.
