# 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.
