+Twisted REST micro-framework
+================================
+
+Based on *Flask* API, with plans for integrated multiprocessing support for full usage of all CPUs. 
+Provides a more Flask/Sinatra-style API on top of the core *twisted.web* APIs.
+Integrates FormEncode for path, form and query argument validation.
+
+An example of a multi--module twisted.web CorePost REST application
+which exposes two separate REST services (for a Customer and Customer Address entities):

+
+Changelog
+`````````
+* 0.0.16:
+    - minor bug fix for issue #4 (serializing object graphs to XML), removed Jinja2 as dependency:
+        https://github.com/jacek99/corepost/issues/4
+* 0.0.15:
+    - minor bug fixes in auto-converting responses to JSON and parsing arguments/paths with unexpectec characters
+* 0.0.14:
+    - automatic parsing of query, form, JSON, YAML and XML arguments: 
+      http://jacek99.github.com/corepost/argument_parsing.html
+* 0.0.13:
+    - perf fix to avoid unnecessary string concatenation when doing URL routing, after code review (thanks to Gerald Tremblay) 
+* 0.0.12:
+    - backwards incompatible change: added advanced URL routing for nested REST services.
+      CorePost object is gone, REST services are now just standard classes.
+      They get wrapped in a RESTResource object (see sample above) when exposed
+* 0.0.11:
+    - added support for request/response filters
+* 0.0.10:
+    - removed dependency on txZMQ which was not needed at this point (yet)
+* 0.0.9:
+     - fix for issue #3 (wrong class passes as 'self' to router method): 
+         https://github.com/jacek99/corepost/issues/3 
+* 0.0.8:
+    - support for serializing of classes to JSON,XML,YAML based on caller's Accept header
+    - separate routing functionality from CorePost Resource object, in preparation for future multicore support
+* 0.0.7:
+    - automatic parsing of incoming content (JSON, YAML, XML)
+    - routing by incoming content type
+    - automatic response conversion based on caller's Accept header (JSON/YAML
+    - support for defer.returnValue() in @inlineCallbacks route methods
+* 0.0.6 - redesigned API around classes and methods, rather than functions and global objects (after feedback from Twisted devs)
+* 0.0.5 - added FormEncode validation for arguments
+* 0.0.4 - path argument extraction, mandatory argument error checking
