   2 #
   3 # This Makefile fragment is included to bsd.pkg.mk and defines the
   4 # relevant variables and targets for the "clean" phase.
   5 #
   6 # The following variables may be set by the package Makefile and
   7 # specify how cleaning happens:
   8 #
   9 #    CLEANDEPENDS specifies the whether "cleaning" will also clean
  10 #       in all dependencies, implied and direct.  CLEANDEPENDS
  11 #       defaults to "no".
  12 #
  13 # The following targets are defined by bsd.pkg.clean.mk:
  14 #
  15 #    clean-depends is the target which descends into dependencies'
  16 #       package directories and invokes the "clean" action.
  17 #
  18 #    do-clean is the target that does the actual cleaning, which
  19 #       involves removing the work directory and other temporary
  20 #       files used by the package.
  21 #
  22 #    clean is the target that is invoked by the user to perform
  23 #       the "clean" action.
  24 #
  25 #    cleandir is an alias for "clean".
