Platform Independent Petri Net Editor project (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively.

A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations.

Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification.

PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.

Scratchlib is a open source platform independent C++ library that can detect the position, speed and direction of Final Scratch timecode records.
Is there a simple example how to use it ?
Yes, just download the sources, compile it and see how it works.
Can i use other timecode records with this library ?
By reason of lack of time there are currently no plans to do this even though we have an idea how to support other systems.
