This book is devoted to the issues of system administration for X and X-based networks, written for anyone faced with the job of administering X (including those running X on stand-alone workstations). The guide is available either alone or packaged with the XCD. The CD provides X source code and binaries to complement the book's instructions for installing the software. It contains over 600 megabytes of X11 source code and binaries stored in ISO9660 and RockRidge formats. This will allow several types of UNIX workstations to mount the CD-ROM as a filesystem, browse through the source code and install pre-built software.
