grml is a Debian-based Live-CD. It includes a collection of GNU/Linux software especially for users of texttools and system administrators. grml provides automatic hardware detection. You can use grml for example as a rescue system, for analyzing systems/networks or as a working environment. It is not necessary to install anything to a harddisk, you don't even need a harddisk to run it, unless you want to (use grml2hd for this). Due to on-the-fly decompression grml includes about 2.1 GiB of software and documentation on the CD.
