[Typo3] How to let a user to clean the cache?

[Rafa]

Hi,
how can I do that a backend user that I configured in my site can have
permission to clean the cache. I have not seen any permission of this kind
to be asigned. I have look for in the documentation and I have lost myself
there...
Thank you very much.
