This is a POSIX binding for LuaJIT, Lua 5.1, 5.2 and 5.3; like most libraries it simply binds to C APIs on the underlying system, so it won't work on non-POSIX systems. However, it does try to detect the level of POSIX conformance of the underlying system and bind only available APIs.
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.
