You forgot this part from that page:

   which you can activate at the command line as `ipython -p pysh'

and indeed:

tlon[~]> ip -p pysh
Python 2.4.4c1 (#2, Oct 11 2006, 21:51:02)
Type "copyright", "credits" or "license" for more information.

IPython 0.7.4.svn.r2010 -- An enhanced Interactive Python.
?       -> Introduction to IPython's features.
%magic  -> Information about IPython's 'magic' % functions.
help    -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

IPython profile: pysh

[...]

tlon[local]|16> $a=ls
tlon[local]|17> a
           <17> 'bin\ninclude\nlib\nman\nshare'
tlon[local]|18> $$b=ls
tlon[local]|19> b
           <19> ['bin', 'include', 'lib', 'man', 'share']
