Comment 1 for bug 1319545

I've created a branch of KARL dev-buildout (<email address hidden>:karlproject/dev-buildout.git) named 'karlserveless'. It removes the dependency on karlserve from the build, and uses a 'karlserveless' branch of the karl package, into which I cut n pasted a bunch of code from karlserve (a root factory, mainly).

Changes on this branch as compared to master:

- karlserve, the package, is not depended upon nor put on the PYTHONPATH.

- karlserve, the command, is no longer available. You start karl via "bin/paster serve etc/karl.ini" rather than "bin/karlserve serve"

- etc/karl.ini is new, etc/karlserve.ini was removed.

- etc/instances.ini was removed. It was an artifact of karlserve.

- a new pg.conf zconfig file is in etc representing the configuration for RelStorage-based deployments. This used to be the domain of karlserve, which would dynamically write such a file.

- Per-instance configuration stored in the database is no longer honored.

A bunch of functionality will need to be reworked for this branch to be merged back to master. In particular, all the non-"serve" parts of karlserve, which are thus:
