#FLM: Get and set font level PostScript hint data.
from robofab.world import CurrentFont
"""
This script shows the way to get to the font level postscript hint values.
These values were available from the fl layer, but not in RoboFab.
Now they're available in RoboFab in a slightly easier to use format.
The values also export to UFO and import from UFO.
Check the FontLab FontInfo panel / Hinting Settings
