# $(STAMP_DIR) houses stamp files for complex targets.

# their files.
DEBTREEDIR:=$(CURDIR)/debian/tmp

# All "important" targets have four lines:
#   1) A target name that is invoked by a package-building tool or the user.
#      This consists of a dependency on a "$(STAMP_DIR)/"-prefixed counterpart.
#   2) A line delcaring 1) as a phony target (".PHONY:").
#   3) A "$(STAMP_DIR)/"-prefixed target which does the actual work, and may
#   depend on other targets.
#   4) A line declaring 3) as a member of the $(stampdir_targets) variable; the
#   "$(STAMP_DIR)/" prefix is omitted.
#
# This indirection is needed so that the "stamp" files that signify when a rule
# is done can be located in a separate "stampdir".  Recall that make has no way
# to know when a goal has been met for a phony target (like "build" or
# "install").
#
# At the end of each "$(STAMP_DIR)/" target, be sure to run the command ">$@"
# so that the target will not be run again.  Removing the file will make Make
# run the target over.

# All phony targets should be declared as dependencies of .PHONY, even if they
# do not have "($STAMP_DIR)/"-prefixed counterparts.
