 987 # Preprocessing rules
 988 #
 989 # The PP_TARGETS variable contains a list of all preprocessing target
 990 # categories. Each category has associated variables listing input files, the
 991 # output directory, extra preprocessor flags, and so on. For example:
 992 #
 993 #   FOO := input-file
 994 #   FOO_PATH := target-directory
 995 #   FOO_FLAGS := -Dsome_flag
 996 #   PP_TARGETS += FOO
 997 #
 998 # If PP_TARGETS lists a category name <C> (like FOO, above), then we consult the
 999 # following make variables to see what to do:
1000 #
1001 # - <C> lists input files to be preprocessed with mozbuild.action.preprocessor.
1002 #   We search VPATH for the names given here. If an input file name ends in
1003 #   '.in', that suffix is omitted from the output file name.
1004 #
1005 # - <C>_PATH names the directory in which to place the preprocessed output
1006 #   files. We create this directory if it does not already exist. Setting
1007 #   this variable is optional; if unset, we install the files in $(CURDIR).
1008 #
1009 # - <C>_FLAGS lists flags to pass to mozbuild.action.preprocessor, in addition
1010 #   to the usual bunch. Setting this variable is optional.
1011 #
1012 # - <C>_TARGET names the 'make' target that should depend on creating the output
1013 #   files. Setting this variable is optional; if unset, we preprocess the
1014 #   files for the 'libs' target.
1015 #
1016 # - <C>_KEEP_PATH may be set to 1 to indicate the paths given in <C> are to be
1017 #   kept under <C>_PATH. That is, if <C> is bar/baz/qux.h.in and <C>_PATH is
1018 #   $(DIST)/include, the preprocessed file would be $(DIST)/include/bar/baz/qux.h
1019 #   instead of $(DIST)/include/qux.h.
