+Introduction
+============
+
+This is the official documentation for IPython 0.x series (i.e. what
+we are used to refer to just as "IPython"). The original text of the
+manual (most of which is still in place) has been authored by Fernando
+Perez, but as recommended usage patterns and new features have
+emerged, this manual has been updated to reflect that fact. Most of
+the additions have been authored by Ville M. Vainio.
+
+The manual has been generated from reStructuredText source markup with
+Sphinx, which should make it much easier to keep it up-to-date in the
+future. Some reST artifacts and bugs may still be apparent in the
+documentation, but this should improve as the toolchain matures.
