Configuration variables for DPM

IMPORTANT NOTE!!: Updated documentation for the configuration of DPM is now under https://twiki.cern.ch/twiki/bin/view/LCG/Site-info_configuration_variables#DPM.

These are all the necessary variables to configure the DPM services (head, disk).

There are two example files coming in /opt/glite/yaim/examples/siteinfo. The site-info.def file, containing general variables and the services directory, containing the node type specific variables. Please, remember to move these files into your appropriate siteinfo directory where you store the YAIM configuration. You can also put all the variables together in the same file. For more details please check The configuration variables section in the YAIM guide.
