ReportLab's templating system

Preppy is ReportLab's templating system. It was developed in late 2000 and has been in continual production use since then. It is open source (BSD-license). The key features are: - *small*. Preppy is a single Python module. If you want a templating system 'in the box', it's easy to include it in your project - *easy to learn*. It takes about one minute to scan all the features - *just Python*. We have not invented another language, and if you want to do something - includes, quoting, filters - you just use Python - *compiled to bytecode*: a .prep file gets compiled to a Python function in a .pyc file - *easy to debug*: preppy generates proper Python exceptions, with the correct line numbers for the .prep file. You can follow tracebacks from Python script to Preppy template and back, through multiple includes - *easy to type and read*. We've been using ``{{this}}`` syntax since well before Django was thought of - *8-bit safe*: it makes no assumption that you are generating markup and does nothing unexpected with whitespace; you could use it to generate images or binary files if you wanted to.
