<P>Text::Wrap::wrap() is a very simple paragraph formatter. It formats a
single paragraph at a time by breaking lines at word boundaries.
Indentation is controlled for the first line ($initial_tab) and
all subsequent lines ($subsequent_tab) independently.</P>
<P>Lines are wrapped at $Text::Wrap::columns columns.
$Text::Wrap::columns should be set to the full width of your output device.</P>
<P>When words that are longer than $columns are encountered, they
are broken up. Previous versions of <CODE>wrap()</CODE> die()ed instead.
To restore the old (dying) behavior, set $Text::Wrap::huge to
'die'.</P>
<P>Text::Wrap::fill() is a simple multi-paragraph formatter. It formats
each paragraph separately and then joins them together when it's done. It
will destroy any whitespace in the original text. It breaks text into
paragraphs by looking for whitespace after a newline. In other respects
it acts like wrap().</P>
