The Heirloom Documentation Tools provide troff, nroff, and related utilities to format manual pages and other documents for output on terminals and printers. They are portable and enhanced versions of the utilities released by Sun as part of OpenSolaris, and, for pic, grap, mpm, and some minor parts, by Lucent as part of Plan 9.
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.
