# Script to build Macintosh Universal Binary library of jpeg-6b for
# use in building BOINC.
#
# by Charlie Fenton 12/19/07
# Updated 2/27/08
#
## In Terminal, CD to the jpeg-6b directory.
##     cd [path]/jpeg-6b/
## then run this script:
##    source [ path_to_this_script ] [ -clean ]
#
# the -clean argument will force a full rebuild.
