# Font Cleanup script v.1.1
#
# This will revert a user's font set to the 10.4 default list
#
# Author: Eddie Kelley <eddie@kelleycomputing.net>
#
# //////////////////////////////////////////////////////////////////////
#
# We need to do each section of Fonts separately (System vs. Library)
# the default list of fonts should be in files next to this script
# and should be named 10.X_SystemFonts.txt and 10.X_LibraryFonts.txt, 
# where X is the minor version of the system - 
# otherwise, the paths for each list should be changed below
#
# Default fonts lists located here:
#
# 10.3: http://docs.info.apple.com/article.html?artnum=25710
# 10.4: http://docs.info.apple.com/article.html?artnum=301332
# 10.5: http://docs.info.apple.com/article.html?artnum=307069
