PatchReader is a set of utilities for reading in, transforming, and doing various other things with a patch. It basically allows you to create a chain of readers that can read a patch, remove files from a patch, add CVS context, fix up the patch root according to CVS, and output the patch as raw unified or through a template processor (used in some places to output a patch as HTML).
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.
