 # TODO(mmoss): Make only supports (theoretically) a single, global build
 # directory (through GYP_GENERATOR_FLAGS 'output_dir'), rather than
 # gyp-file-specific settings (e.g. the stuff in builddir.gypi) that the other
 # generators support, so this doesn't work yet for make.
 # TODO(mmoss) Make also has the issue that the top-level Makefile is written to
 # the "--depth" location, which is one level above 'src', but then this test
 # moves 'src' somewhere else, leaving the Makefile behind, so make can't find
 # its sources. I'm not sure if make is wrong for writing outside the current
 # directory, or if the test is wrong for assuming everything generated is under
 # the current directory.
 # Android does not support setting the build directory.
+# Ninja does not support relocation.
