Ronn builds manuals. It converts simple, human readable textfiles to roff for terminal display, and also to HTML for the web. The source format includes all of Markdown but has a more rigid structure and syntax extensions for features commonly found in manpages (definition lists, link notation, etc.). The ronn-format(7) manual page defines the format in detail.
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.
