Name:	Move to subversion

Vision:
Convert to a source code revision tool that provides the access control
we need while increasing the efficiency of developers access to the
code repository.

Mission statement:

	Replace the CCSM CVS repository with a more modern, easier to use,
more robust, easier to maintain, more flexible Software Configuration
Management versioning system that meets our needs.

Goals:

	Public accessible (i.e. Free) tool.
	Allows developer and public access across Internet.
	Maintains history across directory and file renames
	Maintains a ChangeLog automatically.
	Allows simultaneous development similar to current CVS model.
	Allows several branches of the same code.
	Allows access control to be different across different branches.
	

Motivation:

	Scientists want our code repository to have public versions to
be accessible by all, but some development versions to be restricted.
Everyone also wants the ability to rename files and directories without
the current problems of CVS. We also have technical problems with the
current system that cause loss of productivity.

Plan

	Currently the plan is to use subversion. We've examined 
several of the options, and feel subversion is the best open
source tool to meet our needs at this time. Arch was a possibility,
but it's documentation is lacking and as such subversion looks
like a much better way to go.
