diffpar

FLASH runtime parameter files - often called flash.par - are key-value stores. While the Python API provides functions for manipulating these files, the flmake diffpar command exposes a tool for displaying the difference between two existing parameter files. This is useful in diagnosing what is changed between separate FLASH runs.

USAGE:

flmake diffpar <parfile1> <parfile2>
