 basic funcarg mechanism 
 ==========================================
 
-::
+- provide a "funcarg" maker 
+- and call it for each test function that uses it

+Example test function
+==========================================
+::
 
  def test_somefunction(myarg):
    assert myarg == 'test_somefunction'

+Example conftest.py 
+==========================================
+:: 
+
+ class ConftestPlugin:
+   def pytest_configure(self, config):

 observations
 =====================
 
 funcargs:
 
-* test functions receive value by using a name
+* test functions receive value by specifying a name
 * makers are registered after command line parsing 
 * makers have meta-access to "collected function item"
