18## Common build system definitions.  Mostly standard

20## are used by others to construct the final targets.

29# The short names of all of the targets in the system.
30# For each element of ALL_MODULES, two other variables
31# are defined:
32#   $(ALL_MODULES.$(target)).BUILT
33#   $(ALL_MODULES.$(target)).INSTALLED
34# The BUILT variable contains LOCAL_BUILT_MODULE for that
35# target, and the INSTALLED variable contains the LOCAL_INSTALLED_MODULE.

37# sub-variables.

51# of all targets for a particular tag.  The top-level variable
52# won't have the list of tags;  ust ALL_MODULE_TAGS to get
53# the list of all known tags.  (This means that this variable
54# will always be empty; it's just here as a placeholder for
55# its sub-variables.)
