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