 977 # Preprocessing rules
 978 #
 979 # The PP_TARGETS variable contains a list of all preprocessing target
 980 # categories. Each category has associated variables listing input files, the
 981 # output directory, extra preprocessor flags, and so on. For example:
 982 #
 983 #   FOO := input-file
 984 #   FOO_PATH := target-directory
 985 #   FOO_FLAGS := -Dsome_flag
 986 #   PP_TARGETS += FOO
 987 #
 988 # If PP_TARGETS lists a category name <C> (like FOO, above), then we consult the
 989 # following make variables to see what to do:
 990 #
 991 # - <C> lists input files to be preprocessed with mozbuild.action.preprocessor.
 992 #   We search VPATH for the names given here. If an input file name ends in
 993 #   '.in', that suffix is omitted from the output file name.
 994 #
 995 # - <C>_PATH names the directory in which to place the preprocessed output
 996 #   files. We create this directory if it does not already exist. Setting
 997 #   this variable is optional; if unset, we install the files in $(CURDIR).
 998 #
 999 # - <C>_FLAGS lists flags to pass to mozbuild.action.preprocessor, in addition
1000 #   to the usual bunch. Setting this variable is optional.
1001 #
1002 # - <C>_TARGET names the 'make' target that should depend on creating the output
1003 #   files. Setting this variable is optional; if unset, we preprocess the
1004 #   files for the 'libs' target.
1005 #
1006 # - <C>_KEEP_PATH may be set to 1 to indicate the paths given in <C> are to be
1007 #   kept under <C>_PATH. That is, if <C> is bar/baz/qux.h.in and <C>_PATH is
1008 #   $(DIST)/include, the preprocessed file would be $(DIST)/include/bar/baz/qux.h
1009 #   instead of $(DIST)/include/qux.h.
