LibDBX, part of the ol2mbox project, contains C and a C++ interfaces for accessing Outlook Express dbx files. The C++ interface is just a wrapper for the C interface. It includes two programs. One will read a dbx file and output the emails in mbox format to stdout, the other will read the main "folder.dbx" file and export all the folders into separate mbox files.
afinger is a configurable finger client, written in Perl. It can be used both together with a finger daemon and from the command line. afinger honours a .nofinger file in home directories, you can set a minimum and maximum UID, use a Fortune program for erroneous requests, and virtually control each part of the returned information.
tagbk is a tool that rearranges XBEL bookmark files to improve navigability. It considers every bookmark as if it were tagged with one or more categories, all with the same importance. It does so by mapping the tagged bookmark collection to the usual hierarchic structure, using an algorithm that should create trees that are more intuitive to navigate. This package includes a prototype GUI application for doing collection maintenance using the tagging philosophy.
netplugd monitors one or more network interfaces, running a script when their state changes. The monitored parameters are: whether the interface is interface up or down, whether the interface is running, and whether the link beat is detected (that is, a network cable is plugged in the adapter socket and the hub is on).
