SOAP/REST Mock Service is a simple configurable framework to mock out SOAP or RESTful (or "REST-like") Web services. Its main goal is to support automated integration testing of applications that integrate with 3rd party Web services. Functionality and usage scenarios of the mock service are in a way analogous to unit testing mocking tools (like Mockito or EasyMock). Once properly configured, SOAP/REST Mock Service exposes Web service mocks that can be called from application code and controlled via a REST interface from integration test code (setup, verify, etc.).
Ell is a library to write EBNF grammars as C++ code for quick development of LL(n) parsers or similar applications. It is not a tool to generate parsers (like ANTLR): the grammar you write is directly embedded into your C++ code. The core library is very light (less than 2000 lines of headers) and written in generation templates to achieve the fastest execution. The service provided by Ell is very similar to what Boost Spirit provides, but with a simpler object model, and without the need of the Boost library (it only depends on STL).
