The library provides a logging framework, a serialization/deserialization framework for XML, JSON, CSV, an Ada beans framework, a composition stream framework (raw, files, buffers, pipes, sockets), several concurrency tools (reference counters, counters, pools, fifos, arrays), a REST client framework, and more.
waitcond is a script to specify a combination of events using boolean expressions over various events. It can periodically grep in files, wait for the (dis)appearance of files or processes, wait for certain CPU/net/disk idle values, or wait for an idle tty. waitcond is meant to be combined with some notification tool or system.
