GNU Parted is a package for creating, destroying, resizing, checking, and copying partitions and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data between hard disks, and disk imaging. It contains a library, libparted, and a command-line frontend, parted, which also serves as a sample implementation and script backend.
Gentoo Category Select is a graphical tool for selecting Gentoo Package Categories to exclude from your local package repository. It does so by weaning information from multiple directories and files for convenience, as well as providing warning about categories that should not be excluded due to currently installed packages. This is achieved without the addition of a configuration file. Currently only the Qt front-end is finished. It is modularly designed for ease in creating front-ends based on other toolkits. The advantages are saved disk space (small/MMV), quicker rsync time (small/MMV), and a lessening of bandwidth requirements by gentoo.org and its mirrors.
