What are tags in Subversion?
A tag is just a “snapshot” of a project in time. In Subversion, this idea already seems to be everywhere. Each repository revision is exactly that – a snapshot of the filesystem after each commit. However, people often want to give more human-friendly names to tags, like release-1.0. And they want to make snapshots of smaller subdirectories of the filesystem. After all, it’s not so easy to remember that release-1.0 of a piece of software is a particular subdirectory of revision 4822. Creating a Simple Tag: Once again, svn copy comes to the rescue.
