A book/compact-disc package for the administrator of X and X-based networks. The reader is assumed to be familiar with UNIX and the general principles of system and network administration, and to have copies of the basic references for X close at hand; a knowledge of programming in C is not required, but some programming in the UNIX shell would help. The CD ROM contains over 600 megabytes of related software. Annotation copyright Book News, Inc. Portland, Or.
