Never heard of Eymet before - but they have a really nice website in English here: Eymet Guide - Dordogne Bastide town of Eymet and Region

The number of English language websites that turn up when you google Eymet leads me to believe it may well be one of those British "enclaves" some Brits are trying to avoid in France. A British friend of mine is selling her house in Castelnau, in part because she claims the area has become "too British" for her.
Cheers,
