The format routine will format under all circumstances even if the
width isn't enough to contain the longest words.  *Text::Wrap* will die
under these circumstances, although I am told this is fixed.  If columns
is set to a small number and words are longer than that and the leading
'whitespace' than there will be a single word on each line.  This will
let you make a simple word list which could be indented or right
aligned.  There is a chance for croaking if you try to subvert the
module.  If you don't pass in text then the internal text is worked on,
though not modfied.
*Text::Format* is meant for more powerful text formatting than
*Text::Wrap* allows.  I also have a module called *Text::NWrap* that
is meant as a direct replacement for *Text::Wrap*.  *Text::NWrap*
requires *Text::Format* since it uses *Text::Format->format* to do the
actual wrapping but gives you the interface of *Text::Wrap*.
