        lizard is a simple code complexity analyzer without caring about the
        C/C++ header files or Java imports. It can deal with
        
        -  C/C++
        -  Java
        -  JavaScript
        -  Objective C.
        -  Python
        
        It counts
        
        -  the nloc (lines of code without comments),
        -  CCN (cyclomatic complexity number),
        -  token count of functions.
        -  parameter count of functions.
        
        You can set limitation for CCN (-C), the number of parameters (-a).
        Functions that exceed these limitations will generate warnings. The exit
        code of lizard will be none-Zero if there are warnings.
        
        This tool actually calculates how complex the code 'looks' rather than
        how complex the code real 'is'. People will need this tool because it's
        often very hard to get all the included folders and files right when
        they are complicated. But we don't really need that kind of accuracy for
        cyclomatic complexity.
        
        It requires python2.7 or above (early versions are not verified).
        
        Installation
        ------------
        
        lizard.py can be used as a stand alone Python script, most
        functionalities are there. You can always use it without any
        installation. To acquire all the functionalities of lizard, you will
        need a proper install.
        
        ::
        
           python lizard.py
        
        If you want a proper install:
        
        ::
        
           [sudo] pip install lizard
        
        Or if you've got the source:
        
        ::
        
           [sudo] python setup.py install
        
        Usage
        -----
        
        ::
        
           lizard [options] [PATH or FILE] [PATH] ... 
        
        Run for the code under current folder (recursively):
        
        ::
        
           lizard
        
        Exclude anything in the tests folder:
        
        ::
        
            lizard mySource/ -x"./tests/*"
        
        Options
        ~~~~~~~
        
        ::
        
              --version             show program's version number and exit
              -h, --help            show this help message and exit
              -v, --verbose         Output in verbose mode (long function name)
              -C CCN, --CCN=CCN     Threshold for cyclomatic complexity number warning.
                                    The default value is 15. Functions with CCN bigger
                                    than this number will generate warning
              -a ARGUMENTS, --arguments=ARGUMENTS
                                    Limit for number of parameters
              -w, --warnings_only   Show warnings only, using clang/gcc's warning format
                                    for printing warnings.
                                    http://clang.llvm.org/docs/UsersManual.html#cmdoption-
                                    fdiagnostics-format
              -i NUMBER, --ignore_warnings=NUMBER
                                    If the number of warnings is equal or less than the
                                    number, the tool will exit normally, otherwize it will
                                    generate error. Useful in makefile when improving
                                    legacy code.
              -x EXCLUDE, --exclude=EXCLUDE
                                    Exclude files that match this pattern. * matches
                                    everything, ? matches any single characoter,
                                    "./folder/*" exclude everything in the folder,
                                    recursively. Multiple patterns can be specified. Don't
                                    forget to add "" around the pattern.
              -X, --xml             Generate XML in cppncss style instead of the normal
                                    tabular output. Useful to generate report in Jenkins
                                    server
              -P, --no_preprocessor_count
                                    By default, a #if will also increase the complexity.
                                    Adding this option to ignore them
              -t WORKING_THREADS, --working_threads=WORKING_THREADS
                                    number of working threads. The default value is 1.
              -d, --find_duplicates
                                    Find and skip analysis for file duplicates.
              -s, --sort
                                    Sort the warning with field. The field can be nloc, 
                                    cyclomatic_complexity, token_count, parameter_count,
                                    etc. Or an customized file.

        Using lizard as Python module
        -----------------------------
        
        You can also use lizard as a Python module in your code:
        
        .. code:: python
        
            >>> import lizard
            >>> i = lizard.analyze_file("../cpputest/tests/AllTests.cpp")
            >>> print i.__dict__
            {'nloc': 9, 'function_list': [<lizard.FunctionInfo object at 0x10bf7af10>], 'filename': '../cpputest/tests/AllTests.cpp'}
            >>> print i.function_list[0].__dict__
            {'cyclomatic_complexity': 1, 'token_count': 22, 'name': 'main', 'parameter_count': 2, 'nloc': 3, 'long_name': 'main( int ac , const char ** av )', 'start_line': 30}
        
        You can also use source code string instead of file. But you need to
        provide a file name (to identify the language).
        
        .. code:: python
        
            >>> i = lizard.analyze_file.analyze_source_code("AllTests.cpp", "int foo(){}")
        
        Whitelist
        ---------
        
        If for some reason you would like to ignore the warnings, you can use
        the whitelist. Add 'whitelizard.txt' to the current folder, then the
        functions defined in the file will be ignored. This is an example
        
        ::
        
           #whitelizard.txt
           #The file name can only be whitelizard.txt and put it in the current folder.
           #You may have commented lines begin with #.
           function_name1, function_name2 # list function names in mulitple lines or split with comma.
           filename:function1, function2  # you can also specify the filename
        
        Options in Comments
        -------------------
        
        You can use options in the comments of the source code to change the
        behavior of lizard. By putting "#lizard forgives" inside a function or
        before a function it will suppress the warning for that function.
        
        ::
        
           int foo() {
               // #lizard forgives the complexity
               ...
           }
        
        Wishlist (The features that will come in the near future)
        ---------------------------------------------------------
        -  Support Python & Ruby
        
        Change Logs
        -----------
        
        -  2014.04.07 Remove option -e (display function end line), and make it default
        -  2014.04.06 Remove option -d (ignore duplicated content), and make it default
        -  2014.04.06 Remove option -p (no preprocessor count), and a '#if' will always be counted in cyclomatic complexity
        -  2014.03.31 Support JavaScript!
        -  2014.03.22 Change the -v (--verbose) option to -V. This is because -v
           will be used for --version.
