+.. py:function:: pydu.inspect.getargspec(func)
+  Get the names and default values of a function's arguments.
+
+  A tuple of four things is returned: (args, varargs, varkw, defaults).
+  ``args`` is a list of the argument names (it may contain nested lists).
+  ``varargs`` and ``varkw`` are the names of the * and ** arguments or None.
+  ``defaults`` is an n-tuple of the default values of the last n arguments.
+
+  >>> from pydu.inspect import getargspec
+  >>> def f(a, b=1, *c, **d):
+  ...     pass
+  >>> getargspect(f)
+  ArgSpec(args=['a', 'b'], varargs='c', keywords='d', defaults=(1,))
