Acora is 'fgrep' for Python, a fast multi-keyword text search engine. Based on a set of keywords, it generates a search automaton (DFA) and runs it over string input, either unicode or bytes. It is based on the Aho-Corasick algorithm and an NFA-to-DFA powerset construction. Acora comes with both a pure Python implementation and a fast binary module written in Cython. However, note that the current construction algorithm is not suitable for really large sets of keywords (i.e. more than a couple of thousand).
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.
