FISH Scripting:
- FISH is a scripting is a programming language embedded within FLAC that enables the user to define new variables and functions.
- These functions may be used to extend FLAC’s usefulness or add user defined features (e.g., servo-control boundaries may be applied to a numerical test, unusual property distributions specified, and parameter studies automated).
