>From the README:

 To install system-wide:

 $ python setup.py install   # change python to python2.3 if 2.2 is default

 To install in your home directory (~/bin and ~/lib, actually), run:

 $ python2.3 setup.py install --home=~
 $ export PYTHONPATH=${HOME}/lib/python  # add this to your .bashrc
 $ export PATH=${HOME}/bin:$PATH         # 

 And finally:

 $ hg                                    # test installation, show help

 If you get complaints about missing modules, you probably haven't set
 PYTHONPATH correctly.
