### WIP macOS build script for Work Sans Upright and Italic VF, based on a build script by Mike LaGuttuta
# To add brace trick glyphs, define them in $BraceGlyphs variable, and export the VF from Glyphs App in the same folder as the script

# Setting the Source and VF name, determine if it's for Italic or Upright source from the argument passed to this script
