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.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
