# generate a .ttf file from a set of .svg files
#
# before running this script, create a blank font file in Fontforge
# (make a New font and save it as it is) and change the BLANK_FONT location
#
# you might also want to edit the metadata (title, license, etc.) before
# saving it, or just edit the blank.sfd file afterwards
#
# finally, change the LETTERS_DIR value to the folder where your .svg
# files are; they ought to be named according to their unicode value
