# Ugly little Bash script, generates a set of .h files for GFX using
# GNU FreeFont sources.  There are three fonts: 'Mono' (Courier-like),
# 'Sans' (Helvetica-like) and 'Serif' (Times-like); four styles: regular,
# bold, oblique or italic, and bold+oblique or bold+italic; and four
# sizes: 9, 12, 18 and 24 point.  No real error checking or anything,
# this just powers through all the combinations, calling the fontconvert
# utility and redirecting the output to a .h file for each combo.

# Adafruit_GFX repository does not include the source outline fonts
# (huge zipfile, different license) but they're easily acquired:
# http://savannah.gnu.org/projects/freefont/
