The Perl 5 module Class::Adapter is intended as an abstract base class for creating any sort of class or object that follows the Adapter pattern. An Adapter in this Perl sense of the term is when a class is created to achieve by composition (objects containing other object) something that can't be achieved by inheritance (sub-classing).
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.
