Please note that version 1.2.x is completely incompatible with old parseLib code. The templates should all work, however the API has changed extensively, so you'll just have to re-write any old code. See layout.tmpl for examples of writing templates.
Sections can contain variables.
Prsently there is next to no error checking when opening a template file. This will cause a limited amount of confusion if you're just getting started with ParseLib, and working through your code.
