The CVS is an open system for a version control. Any mathematical programmer is welcome to join with the committer team of OpenXM. The CVS web is used for reading the source tree and the change logs. The cvsup server is used to synchronize the local source tree with the main source tree. These software tools are used to develop free software packages like the FreeBSD operating system. These tools are very useful in development of the OpenXM mathematical software package by a team.
