This is Debian GNU's prepackaged version of xplanet, a program to render images of the earth. This package was put together first by James Troup , from the sources, which he obtained from http://www.alumni.caltech.edu/~hari/xplanet/. The changes were minimal, namely: - adding support for the Debian package maintenance scheme, by adding various debian/* files. - tkxplanet.in: fix a typo (s/--markerfile/--marker_file) which was causing the marker files option not to work. - tkxplanet.1: new manpage. The debian package for xplanet was later maintained by Gopal Narayanan and Christoph Berg . xplanet is now available at http://xplanet.sourceforge.net/ Program Copyright (C) 1999-2002 Hari Nair .
