       By default the output format is hexadecimal.

       By default data is dumped to standard output.  It is possible  to  dump
       data  to	other file by specifying -o option.  In	this case data will be
       appended	to this	file.

       Using -r	option you can specify number of blocks/bytes/data chunks  us-
       ing special text	format.	 See RANGE section for details.

   Available options:
       -b, --binary

       -r, --range <range>

       type or either number of	bytes or number	of data	chunks	for  log  pool
       type.

       -c, --chunk <size>

       Size  of	chunk for log pool type.  See pmemlog_walk(3) in libpmemlog(7)
       for details.

       -o, --output <file>

       <first>-

       All blocks/bytes/data chunks starting from _first_ will be dumped.

       <number>

       Dump  block  number  1 and blocks from 10 to 100	from pool_blk.bin con-
       taining pmem blk	pool to	output.bin file
