# The intended user-driven targets are:
#
# buildworld  - rebuild *everything*, including glue to help do upgrades
# quickworld  - skip the glue and do a depend+build on the meat
# realquickworld - skip the glue and depend stages and just build the meat
# crossworld  - only build the glue (particularly the cross-build environment)
# installworld- install everything built by "buildworld"
# most        - build user commands, no libraries or include files
# installmost - install user commands, no libraries or include files
#
# Standard targets (not defined here) are documented in the makefiles in
# /usr/share/mk.  These include:
#		obj depend all install clean cleandepend cleanobj

# Building a world goes through the following stages
#
# 1. bootstrap-tool 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-tool stage [TMAKE]
#	This stage is responsible for creating the object
#	tree and building any tools that are needed during
#	the build process.
# 3. cross-tool stage [XMAKE]
#	This stage is responsible for creating any tools that
#	are needed for cross-builds. A cross-compiler is one
#	of them.
# 4. world stage [WMAKE]
#	This stage actually builds the world.
# 5. install stage (optional) [IMAKE]
#	This stage installs a previously built world.

# From here onwards are utility targets used by the 'make world' and
# related targets.  If your 'world' breaks, you may like to try to fix
# the problem and manually run the following targets to attempt to
# complete the build.  Beware, this is *not* guaranteed to work, you
# need to have a pretty good grip on the current state of the system
# to attempt to manually finish it.  If in doubt, 'make world' again.
#

# bootstrap-tools: Build all tools required to build all tools.  Note that
# order is important in a number of cases and also note that the bootstrap
# and build tools stages have access to earlier binaries they themselves
# had generated.
#
# patch:	older patch's do not have -i.  This program must be built
#		first so other bootstrap tools that need to apply patches
#		can use it.
# [x]install:	dependancies on various new install features
# rpcgen:	old rpcgen used a hardwired cpp path, newer OBJFORMAT_PATH
#		envs are not compatible with older objformat binaries.
