AutoOpts is an integrated part of AutoGen. Based on a very simple option description file, it will process configuration files, environment variables, command line options, text strings passed by client programs, and will make the results easily accessible to the client program. It will also produce a man page and the info-doc invoking section automatically.
Awka is both a translator of AWK programs to ANSI C, and a separate library against which the C code is linked. The aims of Awka are to allow creation an executable that provides generally better performance than AWK interpretors, to allow easy inclusion of AWK logic in larger C applications, and use of external C functions within AWK scripts.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
The Event monitor project is an approach to network management based on message passing between manager and managed nodes. It's based on a client/server platform, where the server is the manager node, and all clients are managed nodes. This tool is under development, but has lots of features implemented, like a graphical console, message passing layer, one disk monitor and clients for sending messages (both API and binary forms are provided).
Heartbeat is a full-function high-availability system for Linux and other POSIX-like OSes. It monitors services and restarts them on errors. When managing a cluster (more than 1 machine), it will also monitor the members of the cluster and begin recovery of lost services in less than a second. It runs over serial ports and UDP broadcast/multicast, as well as OpenAIS multicast. It is easily adapted to different interconnect media and protocols. When used in a cluster, it can operate using shared disks, data replication, or no data sharing. Versions starting with 2.0 are comparable to any commercial HA package, providing resource monitoring, larger clusters, and detailed dependency information.
x10ephem computes sunrise and sunset times. It consists of a library and an assortment of utilities. The most useful utility is x10events, which parses crontab files and updates the time fields to track sun events. Combined with an X10 interface like HEYU or X10, this allows the scheduling of lighting events to follow the changing seasons and daylight savings time automatically. This application does not depend on X10; it can be used for any crontab entry you like.
bashlib is a shell script that makes CGI programming in bash easier, or at least more tolerable. It contains a few functions that get called automatically to parse incoming form parameters, keywords, and cookies, and builtin functions to access this data. It is very well documented and can be extended very easily.
