=head1 NAME

Acme::Cow::TextBalloon - A balloon of text

=head1 SYNOPSIS

  use Acme::Cow::TextBalloon;

  $x = new Acme::Cow::TextBalloon;
  $x->add("bunch of text");
  $x->wrapcolumn(29);

  $y = new Acme::Cow::TextBalloon;
  $y->adjust(0);
  $y->add("more text");

=head1 DESCRIPTION

C<Acme::Cow::TextBalloon> Creates and manipulates balloons of text,
optionally printing them.  One may notice that the methods in this
module are named very similarly to those in C<Acme::Cow>; that's
because most of them have to do with the balloon rather than the
cow.
