# The intended user-driven targets are:

# installworld- install everything built by "buildworld"
# update      - convenient way to update your source tree (eg: cvsup/cvs)
#
# Standard targets (not defined here) are documented in the makefiles in
# /usr/share/mk.  These include:
#		obj depend all install clean cleandepend cleanobj

# We must do share/info early so that installation of info `dir'
# entries works correctly.  Do it first since it is less likely to
# grow dependencies on include and lib than vice versa.
#
# We must do lib and libexec before bin, because if installworld
# installs a new /bin/sh, the 'make' command will *immediately*
# use that new version.  And the new (dynamically-linked) /bin/sh
# will expect to find appropriate libraries in /lib and /libexec.
#
# We must do etc last for install/distribute to work.

# 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.
# 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.
# 3. cross-tools 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.
