---- Do you tell your client what framework you build on?

does it really matter?
If you are not hosting the site, I say definitely yes. It may require additional work to coordinate with the hosting company to make sure everything is configured properly.
If you are hosting the site yourself (so you will be dealing with all the configuration/updates yourself), I'd still say yes. If the client thinks you're building a site from scratch, then later find out that you used a CMS and (in their eyes) just pushed a few buttons and added some content, most likely they're going to feel ripped off.
State it in the contract. They may not have any interest, but then again, they might.
