The ultimate quest of this module is to produce from non-XML text text, that will will most probably pass through any XML parser one could find. Basic cleaning is just XML tag matching (for every opening tag there will be closing tag as well, and they will form a tree structure). When you add some extra parameters, you will receive complete XML text, including XML head and root element (if none were defined in text, then some will be added).
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.
