Added a comment about from where to start that application.
If get_nth_partition/session_info() returns with anything else than a B_ENTRY_NOT_FOUND, an error message is printed out. The device name can now be specified on the command line, added shortcuts to identify a particular device, i.e. "cd-1-slave" or "slave1-cd" or "1-atapi-slave" would be expanded to /dev/disk/ide/atapi/1/slave/0/raw. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2521 a95241bf-73f2-0310-859d-f6bbb57e9c96
