+Eclipse error parsers
+=====================
+
+These are a godsend for extracting  & quickly navigating to
+warnings & error messages from console output. Unforunately
+I don't know how to write an Eclipse plugin so you'll have
+to add them manually.
+
+To add a console parser to Eclipse, go to Window --> Preferences
+--> C/C++ --> Build --> Settings. Click on the 'Error Parsers'
+tab and then click the 'Add...' button. See the table below for
+the parser fields to add.
+
+Eclipse will only parse the console output during a build, so
+running your unit tests must be part of your build process.
+Either add this to your make/rakefile, or add it as a post-
+build step in your Eclipse project settings.

+This Framework is an optional add-on to Unity.  By including unity_framework.h in place of unity.h,
+you may now work with Unity in a manner similar to CppUTest.  This framework adds the concepts of 
+test groups and gives finer control of your tests over the command line.
