#
# This Makefile fragment is included to bsd.pkg.mk and defines the
# relevant variables and targets for the "clean" phase.
#
# The following variables may be set by the package Makefile and
# specify how cleaning happens:
#
#    CLEANDEPENDS specifies the whether "cleaning" will also clean
#	in all dependencies, implied and direct.  CLEANDEPENDS
#	defaults to "no".
#
# The following targets are defined by bsd.pkg.clean.mk:
#
# clean-depends:
#	descends into dependencies' package directories and invokes the
#	"clean" action.
#
# do-clean:
#	does the actual cleaning, which involves removing the work
#	directory and other temporary files used by the package.
#
# clean:
#	is invoked by the user to perform the "clean" action.
#
# cleandir:
#	an alias for "clean".
#
