# This script downloads System 7.0.1 image from Apple and extracts fonts
# from it. Mac only, unfortunately.
#
# On Windows you perhaps can perform the extraction manually with use of
# HFSxplorer: http://www.catacombae.org/hfsexplorer/
#
# More information could be found in the vMac documentation: http://www.gryphel.com/c/image/
#
# Alternatively you may use vMac instructions for extracting these disk images:
#   http://www.gryphel.com/c/minivmac/recipes/sys7inst/
#
# Based on instructions posted at
# http://apple.stackexchange.com/questions/58243/can-i-get-the-original-mac-font-chicago-on-a-mountain-lion-mac
