The birds are singing, the flowers are budding, and it is time for Miss
Manners to tell young lovers to stop necking in public.

It’s not that Miss Manners is immune to romance. Miss Manners has been
known to squeeze a gentleman’s arm while being helped over a curb, and,
in her wild youth, even to press a dainty slipper against a foot or two
under the dinner table. Miss Manners also believes that the sight of
people strolling hand in hand or arm in arm or arm in hand dresses up a
city considerably more than the more familiar sight of people shaking
umbrellas at one another. What Miss Manners objects to is the kind of
activity that frightens the horses on the street …

I can’t find any (real) documentation, either, but:

irb(main):001:0> require ‘digest/md5’
=> true
irb(main):002:0> Digest::MD5.new(‘apple’) ==
‘1f3870be274f6c49b3e31a0c6728957f’
=> true

the top center frame.

Actually I did just that to be able to guess how to calculate the hash and
it’s certainly much better than no documentation at all, but it’s not
what I’d call ‘real’ documentation for the module.

There’s ruby/ext/digest/digest.txt in the source distribution, which
I’ll fold into the source code one day, whereupon it will appear in

Cheers,
