#
# Building a world goes through the following stages
#
# 1. legacy stage [BMAKE]
#	This stage is responsible for creating compatibility
#	shims that are needed by the bootstrap-tools,
#	build-tools and cross-tools stages. These are generally
#	APIs that tools from one of those three stages need to
#	build that aren't present on the host.
# 1. bootstrap-tools stage [BMAKE]
#	This stage is responsible for creating programs that
#	are needed for backward compatibility reasons. They
#	are not built as cross-tools.
# 2. build-tools stage [TMAKE]
#	This stage is responsible for creating the object
#	tree and building any tools that are needed during
#	the build process. Some programs are listed during
#	this phase because they build binaries to generate
#	files needed to build these programs. This stage also
#	builds the 'build-tools' target rather than 'all'.
# 3. cross-tools stage [XMAKE]
#	This stage is responsible for creating any tools that
#	are needed for building the system. A cross-compiler is one
#	of them. This differs from build tools in two ways:
#	1. the 'all' target is built rather than 'build-tools'
#	2. these tools are installed into TMPPATH for stage 4.
# 4. world stage [WMAKE]
#	This stage actually builds the world.
# 5. install stage (optional) [IMAKE]
#	This stage installs a previously built world.

# programs used during the build accept different flags or generate different
# output. On those platforms we only symlink the tools known to be compatible
# (e.g. basic utilities such as mkdir) into ${WORLDTMP} and build all others
# from the FreeBSD sources during the bootstrap-tools stage.
# We want to build without the user's $PATH starting in the bootstrap-tools
# phase so the tools used in that phase (ln, cp, etc) must have already been
# linked to $WORLDTMP. The tools are listed in the _host_tools_to_symlink
# variable in tools/build/Makefile and are linked during the legacy phase.
# Since they could be Linux or MacOS binaries, too we must only use flags that
# are portable across operating systems.

# In the following, the first 'rm' in a series will usually remove all

# files with file flags set, so this unsets them and tries the 'rm' a
# second time.  There are situations where this target will be cleaning
# some directories via more than one method, but that duplication is
# needed to correctly handle all the possible situations.  Removing all
# files without file flags set in the first 'rm' instance saves time,
# because 'chflags' will need to operate on fewer files afterwards.
#
# It is expected that BW_CANONICALOBJDIR == the CANONICALOBJDIR as would be
# created by bsd.obj.mk, except that we don't want to .include that file
