 * The login machines are installed with a wide set of software that can be uploaded on demand.

 * Different software stacks can be managed by the user through the '''Module''' application. This software initiates the appropriate environment (''PATH, LD_LIBRARY_PATH, etc.''), and is a convenient tool for software transitions.

 * The main commands are:
  * Query available software modules: ''' module avail '''
  * Load a given software module: ''' module load <modulename>'''
  * Unload a given software module: ''' module load <modulename>'''
  * List software in use : ''' module list '''
  * Help on command module : ''' module help'''

 * Specific software for individual group should be installed at the /exper-sw/ areas. 


 * WLCG groups (CMS and ATLAS) have the experiments software available at the CVMFS areas.
