uncsv is a filter command converting the lines of a CSV file into a non‐escaped, non‐quoted delimited file (pipe by default). csv is the opposite of this command; it takes an un-quoted stream of values, separated by the delimiter of your choice (default: pipe ’|’) and produces a "standard" CSV file. Both tools avoid end‐of‐line character politics and will leave these untouched.
s6-networking is a collection of small Unix tools designed to help networking. It includes clock synchronization, Unix and TCP super-servers, Unix and TCP access control, and other miscellaneous utilities. It is particularly suited for management of clients and servers on embedded devices, but works just as well on larger systems.
s6-dns is a small, efficient, complete, and IPv6-ready DNS client library, with synchronous as well as asynchronous APIs. It is designed to replace libresolv in projects that need to perform DNS resolution. It also comes with small command-line utilities to make common and not so common DNS queries.
Finit is a small SysV init replacement with process supervision similar to that of daemontools and runit. Its focus is on small and embedded GNU/Linux systems, although it is fully functional on standard server and desktop installations. Finit is fast because it starts services in parallel; it then supervises and automatically restarts them if they fail. This can be extended upon with custom callbacks for all services, hooks into the boot process, or plugins to extend the functionality and adapt Finit to your needs. Finit is not only fast, it’s arguably one of the easiest to get started with. A complete system can be booted with one simple configuration file.
clens is a convenience library that aids in porting code from OpenBSD to different operating systems. Operating systems traditionally have different enough APIs that porting code is painful and can litter pretty code with ugly #ifdefs. In order to keep code readable and drastically reduce the number of #ifdefs needed, clens brings other APIs or missing functions into specific OS "focus".
xmlsd is a library that wraps expat in order to simplify XML use in C programs as well as adding rigid rules to an XML structure. The idea is to have XML structures that can be passed over the network with implicit parameter verification. This in turn enables back and forth chattering between applications.
