+/*
+** Weclome to Metadesk!
+** 
+** Metadesk is a data description language designed to look like a programming
+** language, and this is the accompanying parser library. While you are free to
+** use it however you see fit, here are a couple of the uses we have intended
+** to support:
+**  + quickly writing a C or C++ metaprogram from scratch
+**  + building "low budget" domain specific scripting languages, such as
+**    marked-up website content, or asset metadata
+**  + creating robust and flexible config systems for applications
+** 
+** If it's your first time working with metadesk you may want to take a look at
+** the examples included with library. The examples_directory.txt file will
+** help you find your way to intro content, and to whatever more advanced
+** aspects of the library you might like to learn more about.
+** 
+** Direct issues, questions, suggestions, requests, etc to:
+** https://github.com/Dion-Systems/metadesk
+**
