7.2.71 Text::Wrap - Wrap Text into a Paragraph

use Text::Wrap;

$Text::Wrap::columns = 20; # default is 76
$pre1 = "\t";              # prepend this to first line of paragraph
$pre2 = "";                # prepend this to subsequent lines
print wrap($pre1, $pre2, "Hello, world, it's a nice day, isn't it?");

This module is a simple paragraph formatter that wraps text into a paragraph and indents each line. The single exported function, wrap(), takes three arguments: a string to prepend to the first output line; a string to prepend to each subsequent output line; and the text to be wrapped.

$columns is exported on request.
