+Wcstools is a set of software utilities, written in C, which create,
+display and manipulate the world coordinate system of a FITS or IRAF
+image, using specific keywords in the image header which relate pixel
+position within the image to position on the sky.  Auxiliary programs
+search star catalogs and manipulate images.
