6# universe - *Really* build *everything* (buildworld and
7# all kernels on all architectures).
8# buildworld - Rebuild *everything*, including glue to help do
9# upgrades.
10# installworld - Install everything built by "buildworld".

107# This 'realclean' target is not included in TGTS, because it is not a
108# recursive target. All of the work for it is done right here. It is
109# expected that BW_CANONICALOBJDIR == the CANONICALOBJDIR as would be
110# created by bsd.obj.mk, except that we don't want to .include that file
111# in this makefile.
112#
113# In the following, the first 'rm' in a series will usually remove all
114# files and directories. If it does not, then there are probably some
115# files with chflags set, so this unsets them and tries the 'rm' a
116# second time. There are situations where this target will be cleaning
117# some directories via more than one method, but that duplication is
118# needed to correctly handle all the possible situations.
