I've been suggesting that folks put them in registry.settings. > > If they do want to put something into the registry, what's the syntax? It's the ZCA API.

You can do this as well, although if you assign the "wrong" value it may break the system. Better to use settings. - C -- You received this message because you are subscribed to the Google Groups "pylons-devel" group. To post to this group, send email to pylons-devel@googlegroups.com.
