+# APWIDTH -- Script to report widths from APALL database files.
+# The input is the image name and database directory.
+# The output is image name, aperture number, x center, y center, and width.

+# To install this script copy it to a directory, such as your IRAF login
+# directory "home$" in this example.  Define the task in your loginuser.cl
+# or login.cl with
+#
+#    task apwidth = home$apwidth.cl
+#
+# Note that you can substitute some other path to the script if desired.
