# Subversion - a Version Control System

Subversion is a collaborative version management system for use with software development or documentation. For more information on Subversion in general, see http://subversion.tigris.org.

WebSVN is available for viewing repositories and the changes to them, here: https://svn.sns.ias.edu/websvn/.

We can set up a Subversion repository for you on request. The resulting repository will be accessible on the Internet, so you may collaborate with others outside IAS. If you would like a repository set up, please send the following to the computing staff:

• Usernames for yourself and and IAS-based collaborators.
• Usernames and passwords for non-IAS collaborators.
• Read/Write access for the users to the project.

Private repositories will usually be accessed on a URL of this form: https://svn.sns.ias.edu/repos/username. We ask that private repositories remain private. If you want others to collaborate, we suggest you choose a project name. Such a repository would be accessed on a URL like this: https://svn.sns.ias.edu/repos/project1.

It is not always necessary to set up a special repository for a given project, because we have made a public one available for all authenticated users. The URL is https://svn.sns.ias.edu/repos/public.
