I recommend getting the text-format module (available from the RAA
at http://rubyforge.org/projects/text-format or as a gem) and using it.

If that doesn't fit your needs for some reason, you can do it manually.
Something like this should work:

words = line.split(/\s+/)
while words do
line = '// '
while words && line.length < 78 do
line += words.shift + ' '
end
puts line
end
