# This test tries to simulate a master/local URL relationship, 
# ie. that there is a "master" URL (to be updated from) and a "local" URL 
# which tracks local modifications.
# 
# The "master" URL is set with a higher priority, so that it takes 
# precedence (binaries, and basic system); the local URL is just for 
# tracking the (machine-specific) local changes.
# 
# We use the working copies as follows:
#  1 for the master data (/trunk in the repository)
WC_MASTER=${WCBASE}1
REP_MASTER=$REPURL
#  2 for the local#1 data (/machineA)
WC_LOCAL1=${WCBASE}2
#  3 for the local#2 data (/machineB)
WC_LOCAL2=${WCBASE}3
#  4 as working copy for machine1
WC_MACHINE1=${WCBASE}4
#  5 as working copy for machine2
WC_MACHINE2=${WCBASE}5
#  6 as the base directory for the machine-specific repositories
REPD_1=${WCBASE}6/m1
REPD_2=${WCBASE}6/m2
REP_1=file://$REPD_1/trunk
REP_2=file://$REPD_2/trunk
# 
# So we need 5 working copies.
NUM_WC=6
#
# We take care to commit to a directory that doesn't yet exist in the 
# "local" repository.

# PS: is there an easier way for variable indirection?
