Description:

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 modified. Text::Format is meant for more powerful text
formatting than Text::Wrap allows.
