The Plain TeX graphics package is mostly a thin shell around the LaTeX graphicx and color packages, with support of the LaTeX-isms in those packages provided by miniltx (which is the largest part of the bundle). The bundle also contains a file "picture.tex", which is a wrapper around the autopict.sty, and provides the LaTeX picture mode to Plain TeX users.
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.
Problem reports, updates or suggestions for this package should be reported with send-pr.
