-# This allows keeping multiple related functions/etc together in one file
-# without forcing linking of unused functions (the GNU linker takes entire
-# object files; it does not currently provide automated dead code removal).
-# Files are split with "#[el]if defined(__SPLIT__<tag>)" lines using normal
-# C preprocessor syntax, where each <tag> must be unique and consist of
-# lowercase alphanumeric and underscore characters only (no dash etc).
-# The makefile function $(split_objs ...) returns the set of objects that
-# result for a given list of splittable source files; each ends in a -.o
-# suffix recognized by special rules further below.
