FAM-Ruby is a Ruby interface to SGI’s File Alteration Monitor (oss.sgi.com/projects/fam/). FAM allows you to monitor files and directories for changes (file modification, creation, and removal) — in an event-driven manner. FAM is available on a variety of platforms, including Irix, Linux, and BSD variants (a patch for systems that use dnotify is also available). As of version 0.2.0, FAM-Ruby can also be used with Gamin (www.gnome.org/~veillard/gamin/), a GNOME library that is compatible with a subset of FAM. An RDoc-generated API reference is available in doc/, and a brief description of each event code is available in event_codes.txt.
