+DESCRIPTION
+
+The \fIWCSINFO\fR task is used to determine the WCS information in an image
+in ways which make it easy for script developers to use specific values
+easily (e.g. the plate center, scale, size, corners, etc).  Images of 
+arbitrary axis mapping and rotation can be used.  If no WCS information
+can be found in the image, the \fIispix\fR parameter will be set to
+'yes'.
+
+
+.ih
+EXAMPLES
+1. Summarize the WCS information about the dev$ypix test image:
+
+.nf
+  votools> wcsinfo dev$ypix
