This program rocks!
If I have
file1, dup11, dup12, dup13
file2, dup21, dup22, dup23
This program will report 12 duplicates, but only 6 in reality.
It will show every combination of file1/dup1* which would be 6 and also same for file2/dup2*.
It would be nice to have a final list saying
file1, dup11, dup21, dup31 are similar
instead of or in addition to saying
file1 and dup11,
file1 and dup12
dup11 and dup12
