Variables: Variabel dimuat dari file konfigurasi

Variables that are loaded from the config files are referenced by enclosing them within #hash_marks#, or with the smarty variable $smarty.config. The later syntax is useful for embedding into quoted attribute values, or accessing variable values such as $smarty.config.$foo.

Contoh
Example config file - foo.conf: pageTitle = "This is mine" bodyBgColor = '#eeeeee' tableBorderSize = 3 tableBgColor = "#bbbbbb" rowBgColor = "#cccccc"
