Template Toolkit 介绍
Template Toolkit 是一个快速、灵活和高可扩展的模板处理系统。可以用来处理各种规模的网页
下面是 Perl 使用该工具的例子：
模板文件内容：
Dear [% name %], It has come to our attention that your account is in arrears to the sum of [% debt %]. Please settle your account before [% deadline %] or we will be forced to revoke your Licence to Thrill. The Management.
源程序：
use Template;
my $tt = Template->new({
INCLUDE_PATH => '/usr/local/templates',
INTERPOLATE => 1,
}) || die "$Template::ERROR\n";
my $vars = {
name => 'Count Edward van Halen',
debt => '3 riffs and a solo',
deadline => 'the next chorus',
};
$tt->process('letters/overdrawn', $vars)
|| die $tt->error(), "\n";
