The installation uses the standard python way (ie also called the distutils way) :

-----------------------------------------
- Default Installation ( as root user ) -
-----------------------------------------

type:

  > python setup.py install

The command line script will be installed in /usr/bin/ (depending of your LINUX distribution), and the different packages will be installed in
your python's "site-packages" directory

-----------------------------------------
-  Custom Installation ( every users )  -
-----------------------------------------

You can also install the package in a custom directory, by specifying :

  > python setup.py install --prefix=<installation-prefix-directory>

The tools will be installed in :
python modules : <installation-prefix-directory>/lib/python
scripts 	     : <installation-prefix-directory>/bin

In this case, do not forget to add  <installation-prefix-directory>/bin to your path for using the command line possibilities.

As an exwample, the tool can be installed with your home directory as prefix :

  > python setup.py install --prefix=$HOME

This way, all will be installed under your home directory and to use the tool, you will just have to eventually update your environment variables :

  > export PATH=$HOME/bin:$PATH
  > export PYTHONPATH=$HOME/lib/python<X.X>/site-packages:$PYTHONPATH

  where <X.X> to your installed python version
