Xnetlib is a new software distribution tool recently developed at the University of Tennessee and Oak Ridge National Laboratory. The goal in developing xnetlib was to provide Internet users faster and easier access to netlib's large collection of software, data, and documents. Unlike netlib, which uses e-mail to process requests for software, xnetlib uses an X Window interface and socket-based communication between the user's machine and the xnetlib server machine to process software requests. This enables users to search through a large distributed collection of software easily and to retrieve requested software in seconds.
