Repoze-retry

---

- Relaxed requirement for ZODB 3.7.2, since we might need to use
the package with other verions.

---

- Depend on PyPI release of ZODB 3.7.2. Upgrade to this by doing
bin/easy_install -U 'ZODB3 >= 3.7.2, < 3.8.0a' if necessary.

---

- Write retry attempts to 'wsgi.errors' stream if availabile.

- Depend on rerolled ZODB 3.7.1 instead of zopelib.

- Add license and copyright, change trove classifiers.

---

- We now buffer the result of a downstream application's
'start_response' call so we can retry requests which have already
called start_response without breaking the WSGI spec (the server's
start_response may only be called once unless there is an exception,
and then it needs to be called with an exc_info three-tuple,
although we're uninterested in that case here).

---

- The entry point name was wrong (it referred to "tm"). Change it so
that egg:repoze.retryretry should work in paste configs.

- Depend on zopelib rather than ZODB 3.8.0b3 distribution, because the
ZODB distribution pulls in various packages (zope.interface and ZEO
most notably) that are incompatible with stock Zope 2.10.4 apps and
older sandboxes. We'll need to revisit this.

---

- Initial release.
