GNU dico is a flexible dictionary server with a set of accompanying utilities. It supports a wide variety of dictionary database formats, ranging from the traditional "dict.org" databases up to Wikipedia format. Support for arbitrary new formats can be easily added using loadable modules. The dico library provides an API for writing new modules in C, Guile, or Python.
DJ Swing Suite provides some components and utilities that are often needed or greatly help the creation of rich Swing user interfaces. The components include, among other things, combo buttons, tri-state check boxes, links, extended label (selectable/multi-line) and text/number fields with support for validation, notification tips, formatters, and masks. The utilities bring features like auto-scroll with middle mouse click, automatic fitting of table columns, and conversion of wildcard expressions.
Secrond is a light-weight cron implementation that allows running of user-specified programs at periodic scheduled times, handling tasks in intervals of seconds rather than minutes, as well as hours and days. While it is possible to achieve similar behavior by using a traditional cron daemon and adding calls to sleep() to the programs executed, it is impractical.
File-Find-Object-Rule is a port of File-Find-Rule to make it use File-Find-Object instead of File::Find. It provides a succinct, declarative syntax for creating directory tree traversal routines while enjoying the advantages of File-Find-Object, such as traversing the tree incrementally and iteratively, and the capability of instantiating several traversers in the same program.
