# 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.
#
# In all cases we must carefully adjust the environment so the proper
# tools and header files are used.
#
# NOTE: The M4 environment variable is used by the [f]lex binary to
#	override the location of the 'm4' binary.  The override is
#	needed for certain buildworld version transitions, specifically
#	past a certain point in 3.3 because the older /usr/bin/m4 will
#	generate output that will blow up the newer [f]lex/yacc/bison
#	utilities.
