Dextep Template Engine implements a template engine based on regular expression replacements. It can process a template with marks that define placeholders or sections using regular expressions to locate and replace those marks. Currently, it supports marks that define expressions, conditions, loops, and sub-templates files. The templates may compiled and cached to avoid processing the templates again in the future.
