ALD is an Assembly Language Debugger written by Patrick Alken. It's released under the GPL and has a familiar feel to it if you're used to GDB. Primary features include stepping, tracing, disassembly, a nice curses-based display, breakpoints, temporary breakpoints, and some library abstractions that people can use in their own software. This package is x86 only at the moment.
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.
