## Common build system definitions.  Mostly standard
## commands for building various types of targets, which
## are used by others to construct the final targets.
##

# These are variables we use to collect overall lists
# of things being processed.

# Full paths to all of the documentation
ALL_DOCS:=

# The short names of all of the targets in the system.
# For each element of ALL_MODULES, two other variables
# are defined:
#   $(ALL_MODULES.$(target)).BUILT
#   $(ALL_MODULES.$(target)).INSTALLED
# The BUILT variable contains LOCAL_BUILT_MODULE for that
# target, and the INSTALLED variable contains the LOCAL_INSTALLED_MODULE.
# Some targets may have multiple files listed in the BUILT and INSTALLED
# sub-variables.
ALL_MODULES:=

# Full paths to targets that should be added to the "make droid"
# set of installed targets.
ALL_DEFAULT_INSTALLED_MODULES:=

# The list of tags that have been defined by
# LOCAL_MODULE_TAGS.  Each word in this variable maps
# to a corresponding ALL_MODULE_TAGS.<tagname> variable
# that contains all of the INSTALLED_MODULEs with that tag.
ALL_MODULE_TAGS:=

# Similar to ALL_MODULE_TAGS, but contains the short names
# of all targets for a particular tag.  The top-level variable
# won't have the list of tags;  ust ALL_MODULE_TAGS to get
# the list of all known tags.  (This means that this variable
# will always be empty; it's just here as a placeholder for
# its sub-variables.)
ALL_MODULE_NAME_TAGS:=

# Full paths to all prebuilt files that will be copied
# (used to make the dependency on acp)
ALL_PREBUILT:=

# Full path to all files that are made by some tool
ALL_GENERATED_SOURCES:=

# Full path to all asm, C, C++, lex and yacc generated C files.
# These all have an order-only dependency on the copied headers
ALL_C_CPP_ETC_OBJECTS:=

# The list of dynamic binaries that haven't been stripped/compressed/prelinked.
ALL_ORIGINAL_DYNAMIC_BINARIES:=

# These files go into the SDK
ALL_SDK_FILES:=

# Files for dalvik.  This is often build without building the rest of the OS.
INTERNAL_DALVIK_MODULES:=

# All findbugs xml files
ALL_FINDBUGS_FILES:=
