LaTeX offers \AtBeginDvi. This package provides the counterpart \AtEndDvi. The execution of its argument is delayed to the end of the document at the end of the last page. At this point \special and \write remain effective, because they are put into the last page. This is the main difference from the LaTeX command \AtEndDocument.
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.
