# Issue 1182: mk-table-checksum not respecting chunk size 
# #############################################################################

# Unfortunately we don't have a good method for testing that the tool
# uses the correct chunks.  That's tested directly in TableChunker.t.
# So here we make sure that --chunk-range doesn't affect anything; it
# should chunk and checksum identically to not using --chunk-range.
