=head1 EXAMPLE: Finding the lowest difference between files
B<diff> is good for finding differences in text files. B<diff | wc -l>
gives an indication of the size of the difference. To find the

B<parallel --tag 'diff {1} {2} | wc -l' ::: * ::: * | sort -nk3>
This way it is possible to see if some files are closer to other
files.
