Term::UI::History
=head1 SYNOPSIS
use Term::UI::History qw[history];
history("Some message");
### retrieve the history in printable form
$hist = Term::UI::History->history_as_string;
### redirect output
local $Term::UI::History::HISTORY_FH = \*STDERR;
=head1 DESCRIPTION
This module provides the C<history> function for C<Term::UI>,
printing and saving all the C<UI> interaction.
Refer to the C<Term::UI> manpage for details on usage from
C<Term::UI>.
This module subclasses C<Log::Message::Simple>. Refer to its
manpage for additional functionality available via this package.
=head1 FUNCTIONS
=head2 history("message string" [,VERBOSE])
Records a message on the stack, and prints it to C<STDOUT>
(or actually C<$HISTORY_FH>, see the C<GLOBAL VARIABLES> section
below), if the C<VERBOSE> option is true.
The C<VERBOSE> option defaults to true.
