The package provided hooks whose arguments are executed just after LaTeX has loaded a new font by means of \selectfont. It has become obsolete with LaTeX versions 2021/01/05 or newer, since LaTeX now provides its own hooks to fulfill this task. For newer versions of LaTeX everysel only provides macros using LaTeX's hook management due to compatibility reasons. See lthooks-doc.pdf for instructions how to use lthooks instead of everysel.
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.
