-Running CMock
-=============
-
-CMock is a Ruby script and class.  You can therefore use it directly from the command line, 
-or include it in your own scripts or rakefiles.  
-
-Mocking from the Command Line
------------------------------
-
-After unpacking CMock, you will find CMock.rb in the 'lib' directory.  This is the file 
-that you want to run.  It takes a list of header files to be mocked, as well as an optional 
-yaml file for a more detailed configuration (see config options below).
-
-For example, this will create three mocks using the configuration specified in MyConfig.yml:
-
-     ruby cmock.rb -oMyConfig.yml super.h duper.h awesome.h
-
-And this will create two mocks using the default configuration:
-
-     ruby cmock.rb ../mocking/stuff/is/fun.h ../try/it/yourself.h
-     
-Mocking From Scripts or Rake
-----------------------------
-
-CMock can be used directly from your own scripts or from a rakefile.  Start by including 
-cmock.rb, then create an instance of CMock.  When you create your instance, you may 
-initialize it in one of three ways.  
-
-You may specify nothing, allowing it to run with default settings:
-
-     cmock = CMock.new
-
-You may specify a YAML file containing the configuration options you desire:
-
-     cmock = CMock.new('../MyConfig.yml')
-
-You may specify the options explicitly:
-
-     cmock = CMock.new('plugins' => ['cexception','ignore'],'mock_path' => 'my/mocks/')
-     
-Config Options:
----------------
-
-The following configuration options can be specified in the yaml file or directly when instantiating.
-
-Option                     Purpose
-----------------------------------------------------------------
-plugins                    An array of which plugins to enable.  'expect' is always active.  
-                           'cexception' and 'ignore' are also currently available.
-                           
-mock_path                  The directory where you would like the mock files generated to 
-                           be placed.
-                           
-includes                   An array of additional include files which should be added to the 
-                           mocks.  Useful for global types and definitions used in your project.
-
-tab                        What does tab mean in your project?  By default: a pair of spaces.
-
-expect_call_count_type     Used internally by CMock... but maybe you don't like int's for 
-                           some reason?
-                           
-ignore_bool_type           Used internally by Ignore plugin... but maybe you have a better 
-                           bool type?
-                           
-cexception_include         Tell cexception plugin where to find Exception.h... only need to 
-                           define if it's not in your build path already.
-                           
-cexception_throw_type      Tell cexception what type you are “throwing” around in your 
-                           application.  It assumes an int 
-
-
-CMock Generated Mock Module Summary
-===================================
-
-In addition to the mocks themselves, CMock will generate the following functions for use in 
-your tests.  The expect functions are always generated.  While the ignore and cexception 
-functions are only generated if those plugins are enabled:
-
-Original Function   => Generated Expect Functions
--------------------------------------------------
-void func(void)     => void func_Expect(void)
-void func(params)   => void func_Expect(expected_params)
-retval func(void)   => void func_ExpectAndReturn(retval_to_return)
-retval func(params) => void func_ExpectAndReturn(expected_params, retval_to_return)
-
-
-Original Function   => Generated CException Functions
------------------------------------------------------
-void func(void)     => void func_ExpectAndThrow(value_to_throw)
-void func(params)   => void func_ExpectAndThrow(expected_params, value_to_throw)
-retval func(void)   => void func_ExpectAndThrow(value_to_throw)
-retval func(params) => void func_ExpectAndThrow(expected_params, value_to_throw)
-
-
-Original Function   => Generated Ignore Functions
--------------------------------------------------
-void func(void)     => void func_Ignore(void)
-void func(params)   => void func_Ignore(void)
-retval func(void)   => void func_IgnoreAndReturn(retval_to_return)
-retval func(params) => void func_IgnoreAndReturn(retval_to_return)
