# run the hdf5/bin/snapshot
# Usage:
#	runtest		run the test for the local host
#	runtest <hostname>	run the test for <hostname>
#	runtest -all		run the test for all predefined hosts
#
# Assumptions in knowing where to find the right scripts to execute.
# 1. assume we are at the top level of the hdf5 source.  So, bin/* are
#    where the script files are.
# 2. after the cvs update is completed, we can go to the snapshot area
#    hdf5 source tree and use the bin/* there.
# 3. Cannot use the snapshot area scripts from the beginning because
#    for one, the current directory is renamed as previous right after
#    a snapshot release; and for another, some scripts may be changed
#    by the cvs update while it is being used.
