textproc/xmlcatmgr 2.2_2 MidnightBSD

XML Catalog Manager (xmlcatmgr in its short form) is a small utility used to manipulate SGML and XML catalogs. It is extremely small and lightweight, specially designed to be run from packaging systems. Basically, it allows adding and removing entries from catalogs in a completely automated way.

A catalog is a lookup mechanism used to translate entities into other different entities. They can, for example, map public identifiers to local files or URIs. This allows you to tell the parser where to look for entities without having to modify the original document source.
