SUPER CATALOG

The super-catalog located in /etc/sgml/catalog cannot be directly modified. It is generated by the update-catalog –update-super command. The generation considers files in the /etc/sgml directory that have a .cat extension. For instance files ending in .old or .disabled are not considered. Before adding a catalog to the super catalog it is parsed and verified in order to not corrupt the super catalog. All referenced catalogs are verified to actually exist. If the check fails, a message is printed and the complete catalog is ignored. This check ensures that a catalog from a package, which is removed but not purged, is removed from the super catalog.
