# These are (at the time of writing) the locations of the most current
# source packages of these utilities.  To drop any of them (I suggest
# that you at least build the first two which are libraries) just
# delete or comment out its definition line.  To add a new package,
# you can add a new XYZ_SRC variable, add it to the build list, and make
# an XYZ_doit.sh script to this directory.
