Eponymous

The Toronto Star website has this puzzling summary of my article (next post) about canapés:
Canapés: a summer treat, a summer scourge

The eponymous finger food snack comes from the greek word for mosquito netting.

I hope the lack of a capital on "Greek" was just an oversight. But what on earth do they think "eponymous" means? "Boycott" is an eponymous word, originating in the name of a Mr. Boycott. If I were to release a CD of me singing (not a hot seller, I'm thinking!) called simply "Katherine", you could call that an eponymous CD. Or if I were to dance the lead role in the ballet Manon (that would be a dream come true for me, if not for the ballet audience, and certainly not for whatever unfortunate guy got to partner me), you could call me the eponymous heroine. But I can't see by any stretch how "eponymous" works in the context above.
