So you just want paragraphs ordered by line count?
Something like this, untested:
perl -00 'print map $_-[0], sort { $a-[1] = $b-[1]
The solution [i asked Randal L. Schwartz, because i didn't worked, and
he said he just forgot the -e, now it works!!]:
perl -00 -e 'print map $_-[0], sort { $a-[1] = $b-[1] } map [$_,

And yes, if you can find expected module in ports tree, it is better
install from ports than install from cpan driectly..
Sometimes we need customized configuration args...
