#
# This trigger script ensures that 'Map:' field on a depot spec is not the 
# unmodified server default, which stores values under the P4ROOT folder.
# The value is set to the standard SDP location for depot storage, but only
# if the current value is the unmodified server default.
#
# Enable this in the triggers table.  On a Linux server, the entry looks
# like this:
#
#   DepotSpecMapField form-out depot "/p4/common/bin/triggers/SetDefaultDepotSpecMapField.py %formfile% 1"
#
# The second paramter, a 1 (one) in the example above, is the instance number.
# If there are multiple Perforce server instances, this trigger should be
# installed in each instance, with the appropriate instance number.
#
# On a Windows server, the triggers table requires an extra argument.  It looks
# like this:
#
#   DepotSpecMapField form-out depot "python <depotdrive>\p4\common\bin\triggers\SetDefaultDepotSpecMapField.py %formfile% 1 <depotdrive>"
#
# where the second parameter is the instance number, and <depotdrive> is the
# drive letter for your depot volume, such as F:
#
# See 'p4 help triggers' for more info.
