=head1 NAME
Bugzilla::Template - Wrapper around the Template Toolkit C<Template> object
=head1 SYNOPSIS
my $template = Bugzilla::Template->create;
$template->put_header($title, $h1, $h2);
$template->put_footer();
my $format = $template->get_format("foo/bar",
scalar($cgi->param('format')),
scalar($cgi->param('ctype')));
=head1 DESCRIPTION
This is basically a wrapper so that the correct arguments get passed into
the C<Template> constructor.
It should not be used directly by scripts or modules - instead, use
C<Bugzilla-E<gt>instance-E<gt>template> to get an already created module.
=head1 SUBROUTINES
=over
=item C<precompile_templates($output)>
Description: Compiles all of Bugzilla's templates in every language.
Used mostly by F<checksetup.pl>.
Params: C<$output> - C<true> if you want the function to print
out information about what it's doing.
Returns: nothing
=back
=head1 METHODS
=over
=item C<put_header($title, $h1, $h2)>
Description: Display the header of the page for non yet templatized .cgi files.
Params: $title - Page title.

$h2 - Page subheader.
Returns: nothing
=item C<put_footer()>
Description: Display the footer of the page for non yet templatized .cgi files.
Params: none
Returns: nothing
=item C<get_format($file, $format, $ctype)>
Description: Construct a format object from URL parameters.
Params: $file - Name of the template to display.
