The Perl 5 module Git::CPAN::Patch provides a suite of git commands aimed at making trivially easy the process of grabbing any distribution off CPAN, stuffing it in a local git repository and, once gleeful hacking has been perpetrated, sending back patches to its maintainer.
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.
