+Abstraction layer over argparse.
+
+
+
+Caipyrinha added 2 methods to argparse.ArgumentParser, ``callback`` and
+``parse_wc``. Also a Caipyrinha instance is callable and is  equal to use
+``parse_wc`` method.
+
+
+Example of use:
+
+.. code-block:: python
+
+    import caipyrinha
+
+    parser = caipyrinha.Caipyrinha(prog="Your Program")
+    parser.add_argument("--version", action='version', version="%(prog)s 0.1")
+
+    @parser.callback(exit=0, group="group1")
+    def first(flags, returns):
+        '''Execute this option and exit'''
+        print "bye bye"
+
+    @parser.callback(action="store")
+    def second(flags, returns):
+        '''set his own return value with his parameter'''
+        return flags.second
+
+    @parser.callback("--third", group="group1")
+    def no_used_name(flags, returns):
+        '''you cant use this argument with first'''
+        print returns.second
+
+    import sys
+    parser(sys.argv[1:])
+
+::
+
+    $ python ex.py --help
+    usage: Your Program [-h] [--version] [--first] [--second SECOND] [--third]
+
+    optional arguments:
+      -h, --help       show this help message and exit
+      --version        show program's version number and exit
+      --first          Execute this option and exit
+      --second SECOND  set his own return value with his parameter
+      --third          you cant use this argument with first
+    $ python ex.py --first
+    bye bye
+    $ python ex.py --first --second "hello from second"
+    bye bye
+    $ python ex.py --first --second "hello from second" --third
+    usage: Your Program [-h] [--version] [--first] [--second SECOND] [--third]
+    Your Program: error: argument --third: not allowed with argument --first
+    $ python ex.py --second "hello from second" --third
+    hello from second
