Documentation
The HTML based documentation, included in the package, addresses the following topics:
- The main part of the document (user tutorial) describes the grammar specification language, special features and how to apply the scanner and parser generator in order to create your own scanner and parser application.
- The reference section explains the (most important) libraray functions as well as the generator and helper programs.
- A few example applications and grammars for some modelling and programming languages are also included in the Styx package.
For more information, please refer to the online documentation.
