   4 # The include file <bsd.subdir.mk> contains the default targets
   5 # for building subdirectories.
   6 #
   7 # For all of the directories listed in the variable SUBDIRS, the
   8 # specified directory will be visited and the target made. There is
   9 # also a default target which allows the command "make subdir" where
  10 # subdir is any directory listed in the variable SUBDIRS.
  11 #
  12 #
  13 # +++ variables +++
  14 #
  15 # DISTRIBUTION  Name of distribution. [base]
  16 #
  17 # SUBDIR        A list of subdirectories that should be built as well.
  18 #               Each of the targets will execute the same target in the
  19 #               subdirectories. SUBDIR.yes is automatically appeneded
  20 #               to this list.

  24 #       distribute:
  25 #               This is a variant of install, which will
  26 #               put the stuff into the right "distribution".
  27 #
  28 #       See ALL_SUBDIR_TARGETS for list of targets that will recurse.
  29 #       Custom targets can be added to SUBDIR_TARGETS in src.conf.
