The following MRU example locates cartridge AQ1Z01 in a TL826 Automated
    Tape Library System.

    $ ROBOT FIND CARTRIDGE AQ1Z01 ROBOT $1$DUA0

    MRU V1.4-1 allows wildcard names for this command as in the
    following examples:

    $ ROBOT FIND CARTRIDGE {"?*"}

    This command shows all elements namely:

    - slots
    - drives
    - transports
    - ports

   that are full.

   $ ROBOT FIND CARTRIDGE {"*"}

   This command shows all slots, drives, transports and ports.
   Irrespective of whether they are full or empty this command
   shows all the elements available in the library.
