AlarPHPTemplate

AlarPhpTemplate is (at least should be) a drop-in replacement for Jaun R.Pozo's PHP-HTML::Template

PHP-HTML::Template is the implementation of a template system for use within PHP scripts, where syntax of templates is the same as that of Sam Tregar's HTML::Template Perl module.

AlarPhpTemplate is a rewritten from scratch and hopefully improved version of it, specifically designed for PHP5.
The more significant improvement is that templates are now stored in compiled state as PHP code, greatly improving speed.
