On second thoughts, don't run "rm -rf" in bsd.clean.mk.  Instead,
document that CLEANFILES and CLEANDIRFILES must not contain
directory names.

# $NetBSD: bsd.clean.mk,v 1.8 2012/11/19 16:04:54 apb Exp $

# <bsd.clean.mk>
#
# Public targets:
#
# clean:	Delete files listed in ${CLEANFILES}.
# cleandir:	Delete files listed in ${CLEANFILES} and ${CLEANDIRFILES}.
#
# Public variables:
#
# CLEANFILES	Files to remove for both the clean and cleandir targets.
#
# CLEANDIRFILES	Files to remove for the cleandir target, but not for
#		the clean target.
#
# MKCLEANSRC	Whether or not to clean the source directory
# 		in addition to the object directory.  Defaults to "yes".
#
# MKCLEANVERIFY	Whether or not to verify that the file deletion worked.
#		Defaults to "yes".
#
# The files listed in CLEANFILES and CLEANDIRFILES must not be
# directories, because the potential risk from running "rm -rf" commands
# in bsd.clean.mk is considered too great.  If you want to recursively
# delete a directory as part of "make clean" or "make cleandir" then you
# need to provide your own target.

# __cleanuse is invoked with ${.ALLSRC} as the name of a variable
# (such as CLEANFILES or CLEANDIRFILES), or possibly a list of
# variable names.  ${.ALLSRC:@v@${${v}}@} will be the list of
# files to delete.  (We pass the variable name, e.g. CLEANFILES,
# instead of the file names, e.g. ${CLEANFILES}, because we don't
# want make to replace any of the file names with the result of
# searching .PATH.)
#
# If the list of files is empty, then the commands
# reduce to "true", with an "@" prefix to prevent echoing.
#
# The use of :M* is needed to handle the case that CLEANFILES
# or CLEANDIRFILES is not completely empty but contains spaces.
# This can easily happen when CLEANFILES or CLEANDIRFILES is set
# from other variables that happen to be empty.)
#
# The use of :Q is needed to handle the case that CLEANFILES
# or CLEANDIRFILES contains quoted strings, such as
# CLEANFILES = "filename with spaces".
