Yes and no.  PyGopherd is capable of presenting ASK blocks to a client, but
is not capable of processing the results itself (the Gopher+ handler does
not support datablocks coming in from the client.)

This was never really an issue because only one client has ever supported
them, and that is UMN gopher, so they are not terribly versatile.

If you want that support, it would not be too hard to add.

Can you post your PYG code for me to take a look at?  Can I assume you are
using UMN gopher as the client?  (All the other protocols will ignore +VIEWS
since they do not support them.)

As a matter of fact, I wrote all that code so long ago I'll have to go back
and double-check it.

PyGopherd does support +VIEWS.  It will return a view selection to your Pyg
as the searchrequest (protocol.searchrequest).

PyGopherd does *NOT* support automatically generating multiple views based
on the contents of a directory and selecting the appropriate file when the
request comes in.  But then, I removed this from UMN gopherd some time back
too, since it is really broken and has lots of side-effects.

In short, PyGopherd provides you with the framework and tools to support
+VIEWS in PYG modules you write, but does not ship with any modules that use
them.

I didn't follow this paragraph, could you be a little more precise?  (Which
file were you patching, etc.)
