   5 # Public targets:
   6 #
   7 # clean:        Delete files listed in ${CLEANFILES}.
   8 # cleandir:     Delete files listed in ${CLEANFILES} and ${CLEANDIRFILES}.
   9 #
  10 # Public variables:
  11 #
  12 # CLEANFILES    Files to remove for both the clean and cleandir targets.
  13 #
  14 # CLEANDIRFILES Files to remove for the cleandir target, but not for
  15 #               the clean target.
  16 #
  17 # MKCLEANSRC    Whether or not to clean the source directory
  18 #               in addition to the object directory.  Defaults to "yes".
  19 #
  20 # MKCLEANVERIFY Whether or not to verify that the file deletion worked.
  21 #               Defaults to "yes".
  22 #
  23 # The files listed in CLEANFILES and CLEANDIRFILES must not be
  24 # directories, because the potential risk from running "rm -rf" commands
  25 # in bsd.clean.mk is considered too great.  If you want to recursively
  26 # delete a directory as part of "make clean" or "make cleandir" then you
  27 # need to provide your own target.
