rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks.

This package provides a client application to query a dictd server. The client-server protocol is TCP-based; the server may then be local or accessed through the network.

colord is a system service that makes it easy to manage, install and generate colour profiles to accurately colour manage input and output devices.

Latexmk runs LaTeX the correct number of times to resolve cross references, etc; it also runs auxiliary programs (bibtex, makeindex if necessary, and dvips and/or a previewer as requested). It has a number of other useful capabilities, for example to start a previewer and then run LaTeX whenever the source files are updated, so that the previewer gives an up-to-date view of the document.
