				# Description:
				# zdb -r <dataset> <path> <destination>
				# Will extract <path> (relative to <dataset>) to the file <destination>
				# Similar to -R, except it does the work for you to find each record
				#
				# Strategy:
				# 1. Create a pool
				# 2. Write some data to a file
				# 3. Append to the file so it isn't an divisible by 2
				# 4. Extract the file
				# 5. Compare the file to the original
				#
