e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
pkgusage lists all the packages you have installed on your system, along with a number telling you how many days ago you last accessed any of the files in the package. This could be useful for cleaning out your hard drive. Pkgusage works with RPMs and Debian packages, and is written to be easily portable to other package managers as well.
The FILTR (File Inventory for Loading, Transfer, and Recovery) automates CVS functions for personal use, allowing a user to maintain a watch on any directory, mirroring it in an intermediate working directory and taking care of all import, add, delete, and update calls to the CVS repository. No changes or additions are made to the directory under watch. The user can revert a watched directory to any previous saved state with a button click, or call up one or several past versions of a file. Groups can also make use of the same repository for file sharing.
