     27 If platform/mac-leopard is missing an expected test output, we fall back on
     28 platform/mac.  This means it's possible to grow redundant test outputs,
     29 where we have the same expected data in both a platform directory and another
     30 platform it falls back on.
     31 
     32 This command dumps out all such files.  You can use it like this:
     33   deduplicate-tests --verbose  # print out the duplicated files
     34   deduplicate-tests | xargs git rm   # delete them
