1454 # The PP_TARGETS variable contains a list of all preprocessing target

1465 #
1466 # - <C> lists input files to be preprocessed with mozbuild.action.preprocessor.
1467 #   We search VPATH for the names given here. If an input file name ends in
1468 #   '.in', that suffix is omitted from the output file name.
1469 #
1470 # - <C>_PATH names the directory in which to place the preprocessed output
1471 #   files. We create this directory if it does not already exist. Setting
1472 #   this variable is optional; if unset, we install the files in $(CURDIR).
1473 #
1474 # - <C>_FLAGS lists flags to pass to mozbuild.action.preprocessor, in addition
1475 #   to the usual bunch. Setting this variable is optional.
1476 #
1477 # - <C>_TARGET names the 'make' target that should depend on creating the output
1478 #   files. Setting this variable is optional; if unset, we preprocess the
1479 #   files for the 'libs' target.
1480 #
1481 # - <C>_KEEP_PATH may be set to 1 to indicate the paths given in <C> are to be
1482 #   kept under <C>_PATH. That is, if <C> is bar/baz/qux.h.in and <C>_PATH is
