    drm4g conf ( daemon | sched | logger ) [ --dbg ]
            
Options:    
    --dbg    Debug mode.

resource:

Manage computing resources on DRM4G.
    
Usage: 
    drm4g resource [ list | edit | check ] [ --dbg ] 
    drm4g resource <name> id conf [ --public-key=<file> --grid-cerd=<file> --lifetime=<hours> --dbg ]
    drm4g resource <name> id init [ --lifetime=<hours> --dbg ]
    drm4g resource <name> id info [ --dbg ]
    drm4g resource <name> id delete [ --dbg ]

Options:
   -l --lifetime=<hours>   Duration of the identity's lifetime [default: 168].
   -p --public-key=<file>  Public key file.
   -g --grid-cerd=<file>   Grid certificate.
   --dbg                   Debug mode.
    
Commands:
   list                    Show resources available.    
   edit                    Configure resources.
   check                   Check out if configured resources are accessible.
   id                      Manage identities for resources. That involves 
                           managing private/public keys and grid credentials, 
                           depending on the resource configuration.
                                           
                           With init, creates an identity for a while, by 
                           default 168 hours (1 week). Use the option --lifetime 
                           to modify this value. It adds the configured private
                           key to a ssh-agent and creates a grid proxy using 
                           myproxy server.
       
                           With conf, initializes an identity (init comnand) 
                           and appends the public key to the remote user's 
                           ~/.ssh/authorized_keys file (creating the file, and 
                           directory, if necessary). It tries to load the public 
                           key obtained by appending *.pub to the name of the 
                           configured private key file. Alternative the public 
                           key can be given by --public-key option.
                           It also configures the user's grid certificate 
                           under ~/.globus directory (creating directory, 
                           if necessary) if --grid-cerd option is used.
                                  
                           With info, it gives some information about the 
                           identity status.
                                
                           With delete, the identity is removed from the 
                           ssh-agent and the myproxy server.
