The package provides macros for manipulating strings -- testing a string's contents, extracting substrings, substitution of substrings and providing numbers such as string length, position of, or number of recurrences of, a substring. The package works equally in Plain TeX and LaTeX (though e-TeX is always required). The strings to be processed may contain (expandable) macros.
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.
