      Description

      mongooplog has a --dbpath option, help message says this:

        --dbpath arg                    directly access mongod database files in the 
                                        given path, instead of connecting to a mongod
                                          server - needs to lock the data directory, 
                                        so cannot be used if a mongod is currently 
                                        accessing the same path

      It's not clear from this message if the dbpath is meant to be used as the SOURCE or the DESTINATION for the oplog operations.

      First I tried using it as the data source:

      test-tools [master●●] % mongooplog --dbpath /tmp/rstest/data_replset0/db4000 --host localhost:4003
      Thu Aug  2 15:45:43 [tools] need to specify --from
      Thu Aug  2 15:45:43 dbexit: 
      Thu Aug  2 15:45:43 [tools] shutdown: going to close listening sockets...
      Thu Aug  2 15:45:43 [tools] shutdown: going to flush diaglog...
      Thu Aug  2 15:45:43 [tools] shutdown: going to close sockets...
      Thu Aug  2 15:45:43 [tools] shutdown: waiting for fs preallocator...
      Thu Aug  2 15:45:43 [tools] shutdown: closing all files...
      Thu Aug  2 15:45:43 [tools] closeAllFiles() finished
      Thu Aug  2 15:45:43 [tools] shutdown: removing fs lock...
      Thu Aug  2 15:45:43 dbexit: really exiting now

      Doesn't work because it seems to still expect a source to be specified with the --from arg.

      I tried with a fresh pair of replsets and tried to use the --dbpath as the destination instead:

      test-tools [master●●] % mongooplog --dbpath /tmp/rstest/data_replset0/db4000 --from localhost:4003
