grml is a live CD originally based on Knoppix and currently based on Debian. It includes a collection of GNU/Linux software especially for users of texttools and system administrators. It provides automatic hardware detection, and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes about 2.1 GB of software and documentation on the CD.
