Thanks for pointing those out. I looked at the source code for Juniper and indeed found the part where it handles introspection: https://github.com/JuniperKernel/JuniperKernel/blob/master/R/inspect_request.R So it basically returns the help as HTML. It seems we can actually return a multi-part MIME message with all sorts of data in it (images, etc.) as well. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
