5 Post Processor
The Post Processor is a Python script used to decode binary log files generated by a
Grasshopper installer.
The Post Processor requires a Grasshopper receipt and the encoded log from its
installation. The Grasshopper log file contains the execution time, a set of all rule
resultsevaluated during installation and return codes for every installation attempt.
When combined with the installer's receipt, the Post Processor is able to decipher
the actions taken by the installer and the results of those actions.
