31 78e51a8c 2005-01-14 devnull system and implements database-like manipulations on sets of such
32 78e51a8c 2005-01-14 devnull objects. It also provides an interface to <a href="../man1/astro.html"><i>astro</i>(1)</a> to plot the
33 78e51a8c 2005-01-14 devnull locations of solar system objects. Finally, it displays images
34 78e51a8c 2005-01-14 devnull from the Space Telescope Science Institute’s Digitized Sky Survey,

38 78e51a8c 2005-01-14 devnull Items are read, one per line, from the standard input and looked
39 78e51a8c 2005-01-14 devnull up in the catalogs. Input is case-insensitive. The result of the
40 78e51a8c 2005-01-14 devnull lookup becomes the set of objects available to the database commands.
41 78e51a8c 2005-01-14 devnull After each lookup or command, if more than two objects are in
