CVS for Mac (without XCode)
If you have Googled for instructions for enabling a CVS client for Mac, you'll probably find that most people suggest using the 'built in' CVS client that comes with Apple's developer tools package XCode. There used to be a way to select only the components in XCode you want to be installed, but with Leopard, you have to install the whole 2.5GB bunch of stuff even if you don't need to use them.
Which is annoying, because all I wanted was a simple CVS client (for checking out Drupal). And here's one such tool: SmartCVS, a standaone CVS client, which is a Java app.Job done.
