Also, ezEdit is very, very, very easy to install and use:
You can add the CMS to your existing website;
You can use it to mock-up updates to your site;
If you are a web designer, you can work on updates with your clients in real-time; and this is without installing anything: simply use the bookmarklet.
ezEdit works as either a very short bootstrap script or a bookmarklet.
The CMS back-end is in a self-contained file as well.
Currently the CMS works with static web pages but it even comes with a plugin architecture that makes it easy to write extensions to update the big guys (Drupal, Wordpress, etc.)
ezEdit is free , open-source and both community and, if demand arises for it, commercially supported.
Using the script is very straightforward as well: a simple hotkey , enter your credentials if security is enabled, and start editing any part of a web page.
Configuration is painless: you can even maintain an external configuration
file if you do not with to open the back-end script.
And, yes, that is correct: you can use the front-end script without the back- end script even being available.
