# Usage :
# This script is intended to be called from script run-basic-tests[.pl]
# The latter starts the test in background mode and waits for
# completion. When done, this script creates a test#.end file if required
#
# Arguments :
#   $TestN = test number (fast, v1, v5, bigdft, etsf_io, libxc, wannier90)
#   $ENDtest = kind of criterion for test completion; supported values are:
#	ps = unix ps command
#	pstat = Windows NT ResKit pstat command
#	numeric = test#.end file with loop limit
#   $SLASH = subdirectory delimitor in file paths
#   $SUFXstyle = defines suffixes style for binaries, ...;
#		supported values are: unix, DOS, vms
#
