Schwartz is a developer tool that takes the pain out of writing complex graphics-drawing code. With Schwartz, you can create vector-based graphic compositions in a user-friendly WYSIWYG environment, and then automatically generate source code for rendering your composition on iOS, OS X, the Web, or any other platform.
But what's unique about Schwartz is that it's **template-based**. Each source code output target is a template that can be edited to your specific syntactical tastes. And adding new templates to support new target languages is extremely easy.
Working with Schwartz templates is a simple and intuitive process, similar to using template languages for popular web application frameworks like Ruby on Rails, Django, or JavaServer Pages.
