This is webcheck, a command line utility for crawling websites. webcheck was originally named linbot which was developed by Albert Hopkins (marduk) . Versions up till 1.0 were maintained by Mike W. Meyer who changed the name to webcheck, http://www.mired.org/webcheck/. After that Arthur de Jong took up the work and did a complete rewrite, http://arthurdejong.org/webcheck/. Arthur de Jong is both the upstream and Debian package maintainer, so there are no differences between the Debian package and the upstream version. The Debian package of webcheck was previously maintained by Bastian Kleineidam . The Debian package of linbot was maintained by Colin Watson , Matej Vela and Jean Pierre LeJacq .
