The "tex-everypage" package provides hooks to perform actions on every page, or on the current page. Specifically, actions are performed after the page is composed, but before it is shipped, so they can be used to prepare the output page in tasks like putting watermarks in the background, or in setting the next page layout, etc.
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.
