# The PP_TARGETS variable contains a list of all preprocessing target
# categories. Each category defines a target path, and optional extra flags
# like the following:
# categories. Each category has associated variables listing input files, the
# output directory, extra preprocessor flags, and so on. For example:
#
# FOO_PATH := target_path
# FOO_FLAGS := -Dsome_flag
# PP_TARGETS += FOO
# FOO := input-file
# FOO_PATH := target-directory
# FOO_FLAGS := -Dsome_flag
# PP_TARGETS += FOO
#
# Additionally, a FOO_TARGET variable may be added to indicate the target for
# which the files and executables are installed. Default is "libs".
# 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 config/Preprocessor.py. 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 Preprocessor.py, 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.
# preprocess_file_template defines preprocessing rules.
