=head1 NAME
Term::Complete - Perl word completion module
=head1 SYNOPSIS
$input = Complete('prompt_string', \@completion_list);
$input = Complete('prompt_string', @completion_list);
=head1 DESCRIPTION
This routine provides word completion on the list of words in
the array (or array ref).
The tty driver is put into raw mode and restored using an operating
system specific command, in UNIX-like environments C<stty>.
The following command characters are defined:
=over 4
=item E<lt>tabE<gt>
Attempts word completion.
Cannot be changed.
=item ^D
Prints completion list.
Defined by I<$Term::Complete::complete>.
=item ^U
Erases the current input.
Defined by I<$Term::Complete::kill>.
=item E<lt>delE<gt>, E<lt>bsE<gt>
Erases one character.
Defined by I<$Term::Complete::erase1> and I<$Term::Complete::erase2>.
=back
=head1 DIAGNOSTICS
Bell sounds when word completion fails.
=head1 BUGS
The completion character E<lt>tabE<gt> cannot be changed.
