copied!<p>You should go through the first few chapters of the Subversion online reference over at <a href="http://svnbook.com" rel="nofollow">http://svnbook.com</a>. This will give you a quick and good start on both version control and Subversion.</p> <p>What you're doing is pretty close to the way Subversion works. Do you have those directories yet?</p> <p>In standard a Subversion setup, you setup a "tags", "branches", and "trunk" directory. Some people set these up on the root of their repository, others set them up under the root of each project.</p> <p>For example:</p> <pre><code>svn://svn/trunk/proj1 svn://svn/trunk/proj2 svn://svn/branches/proj1/1.2 svn://svn/branches/proj2/3.4 </code></pre> <p>or </p> <pre><code>svn://svn/proj1/trunk svn://svn/proj2/trunk svn://svn/proj1/branches/1.2 svn://svn/proj2/branches/3.4 </code></pre> <p>Most sites I've seen do it the last way, but there can be advantages of doing it the first way (mainly due to using <code>svn:externals</code> and the fact when you do a checkout, your checkout isn't called <code>trunk</code> by default).</p> <p>All you need to do is call your "old-versions" directory <code>tags</code> and you're all set:</p> <pre><code>svn://svn/UI/tags/1.0 svn://svn/UI/tags/2.0 svn://svn/UI/tags/2.5 svn://svn/UI/trunk </code></pre> <p>If you forgot to make the tag, panic ye not! One of the great things about Subversion is the revision number of the repository. It's sort of like making a tag every time you do a commit. If you can find the revision number when you did a release (usually through looking at the <code>svn log</code>) you can then copy that revision to create your tag:</p> <pre><code>$ svn cp -r1234 svn://svn/UI/trunk svn://svn/UI/tags/2.0 </code></pre> <p>As you can see, you use the <code>svn cp</code> command to create tags and branches. By the way, it's very easy to modify a tag without realizing it. In most sites, they have a pre-commit hook which either can prevent most users in making commits under the tags directory (this means you have to create the tags) or they allow users to create a tag (via <code>svn cp</code>) but not let users modify a tag once it is created. I have a Perl version of a pre-commit hook at <a href="http://dl.dropbox.com/u/433257/new_svn_hooks.zip" rel="nofollow">http://dl.dropbox.com/u/433257/new_svn_hooks.zip</a> if you want to take a look at it.</p>
