# $FreeBSD$

# The include file <bsd.obj.mk> handles creating the 'obj' directory
# and cleaning up object files, etc.
#
# +++ variables +++
#
# CLEANDIRS Additional directories to remove for the clean target.
#
# CLEANFILES Additional files to remove for the clean target.
#
# MAKEOBJDIR A pathname for the directory where the targets
# are built. Note: MAKEOBJDIR is an *enviroment* variable
# and works properly only if set as an enviroment variable,
# not as a global or command line variable!
#
# E.g. use `env MAKEOBJDIR=temp-obj make'
#
# MAKEOBJDIRPREFIX Specifies somewhere other than /usr/obj to root the object
# tree. Note: MAKEOBJDIRPREFIX is an *enviroment* variable
# and works properly only if set as an enviroment variable,
# not as a global or command line variable!
#
# E.g. use `env MAKEOBJDIRPREFIX=/somewhere/obj make'
#
# NOOBJ Do not create object directories. This should not be set
# if anything is built.
#
# +++ targets +++
#
# clean:
# remove ${CLEANFILES}; remove ${CLEANDIRS} and all contents.
#
# cleandir:
# remove the build directory (and all its contents) created by obj
#
# obj:
# create build directory.
