Thank you. Can you lead this activity? We need somebody who will drive
the discussion and oversee actual changes...

Yeah. I posted a separate message on eCAP that has an alternative to
exposing Squid headers and libraries. Perhaps that would work better.

I do not like the generic says-nothing names "lib" and "include". I also
do not like that the two directories pollute the top-level directory.
Can we, perhaps, agree on something like

The problem with "xFoo" is that other libraries we link with might have
their own "xFoo".

A C++ solution for this is namespaces, I guess, but it would require
more work to implement that approach in a clean way.

How about


It is more specific, shorter, and easier to spell :-).

Any chance to convince you and others that HTTPReply is not as readable
as HttpReply?

If we start using namespaces for protocols, then this becomes a
non-issue because HTTP::Reply reads just fine. Perhaps this should be a
separate question. Should we start using namespaces for protocols and
other important groups? I think we should.

I am not sure that tradition applies to C++ stuff or "modern" code in

Thank you,
