#  main SConstruct for building Hall D online packages
#
# This will simply run scons in each of the directories
# listed in the "packages" variable, passing it a list of the
# arguments given on the command line. It is done this
# way because each package contains it's own SConstruct file
# so that it can be built independently. Reading them in with
# the SConscript routine did not seem to work so this solution
# has been implemented.

# printed only after everything is finished. Otherwise, it
# makes it look like it is still working on stuff.
