This is a program to test the compatibility (or to demonstrate the non-compatibility) of so-called "VT100-compatible" terminals. In conformance of the good old hacker traditions, the only documentation of this program is the source code itself. To understand it, you also need a copy of the original VT100 manual from DEC.
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.
