 +Prerequisites:
 +  * Python (version 2.5 or better)  [[http://www.python.org|python.org]]
 +  * numpy — Numeric Python [[http://www.numpy.org|numpy.org]]
 +  * Additionally (depending on some of the options set):
 +    * scipy — Scientific Python [[http://www.scipy.org|scipy.org]]
 +    * matplotlib
 +  * (Obviously you also need a copy of the Hitran or Geisa line parameter databases)
 +
 +  - Save the package at some convenient place and unpack it: ''tar xvfz lblod4esas.tgz''
 +  - Ideally add the ''bin'' directory to your system search ''PATH''
 +  - If you are reading user guide's etc: in your browser open the ''index.html'' file in the ''doc'' directory;\\ Otherwise just ''extract'' line parameters from HITRAN and GEISA, then compute optical depth via cross sections by ''lbl2od''
