What is it?
-----------


MGTemplateEngine is a native Cocoa system for generating text output based on templates and data. It's a close cousin of systems like Smarty, FreeMarker, Django's template language, and other such systems.


The default syntax for markers (functions or language-constructs) is:


{% for 1 to 5 %} foo {% /for %}


and the default syntax for variables/expressions is:


{{ foo.bar | uppercase }}


The pipe-character indicates a filter is being applied; i.e. the value of "foo.bar" will then be fed to the "uppercase" filter before being displayed. You can apply filters to markers as well as variables.


The marker, variable and filter delimiters are completely customizable, so you're not stuck with the defaults if you prefer different syntax.
