#FLM: Get Data for the Specimen Tool

# Description:
# Get Advance Width and Kerning Pairs data
# Saves two TXT files
# Contents of those filess can be copy-pasted into the specimens tool

# To-do:
# It only report main pairs, not fully expanded if the font uses classes
# Better to run it in a copy of your font, having your kerning manually expanded
