Special exception handling over the wire.
Since we cannot assume that our client is able to import our exception classes,
this module provides a "wrapping" mechanism to raise plain exceptions
which contain an extra attribute `_vcs_kind` to allow a client to distinguish
different error conditions.

from pyramid.httpexceptions import HTTPLocked
def _make_exception(kind, *args):
Prepares a base `Exception` instance to be sent over the wire.
To give our caller a hint what this is about, it will attach an attribute
`_vcs_kind` to the exception.
exc = Exception(*args)
exc._vcs_kind = kind
return exc
