Design notes
------------
+
+When designing ryp2, attention was given to make:
+
+- the use of the module simple from both a Python or R user's perspective
+
+- minimize the need for knowledge about R, and the need for tricks are
workaround.
+- the possibility to customize a lot only with Python (without having to go to
C-level).
+
+
:mod:`rpy2.robjects` implements an extension to the interface in
:mod:`rpy2.rinterface` by extending the classes for R
objects defined there with child classes.

+One point where function calls in R can differ from the ones in
+Python is that

+(no matter whether the parameter is named or not),
+while in Python only parameters without a name are passed in order.

+
+
+Overview
+========
+
+The package proposes R features for a pure Python
+context, that is without an embedded R running.
+
+
+
+Containers
+==========
+.. module:: rpy2.rlike.container
+
+>>> import rpy2.rlike.container as rlc
+
+ArgsDict
+--------
+
+The :class:`ArgsDict` proposes an implementation of what is
+sometimes referred to in Python as an ordered dictionnary, with a
+particularity: a key ``None`` means that, although an item has a rank
+and can be retrieved from that rank, it has no "name".
+
+In the hope of simplifying its usage, the API for an ordered dictionnary
+in :pep:`372` was implemented. An example of usage is:
+
+>>> x = (('a', 123), ('b', 456), ('c', 789))
+>>> nl = rlc.ArgsDict(x)
+
+
+>>> nl['a']
+123
+>>> nl.index('a')
+0
+
+Not all elements have to be named, and specifying a key value equal
+to `None` indicates a value for which no name is associated.
+
+
+>>> nl[None] = 'no name'
+
+
+
+TaggedList
+----------
+
+A :class:`TaggedList` is a Python list in which each item has
+an associated tag.
+This is similar to `named` vectors in R.
