 #
 # 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.

 # Since they could be Linux or MacOS binaries, too we must only use flags that

 # 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.
