-// The conundrum: libdimension and libdimension-* use C I/O, with FILE*'s.
-// We want to use C++ I/O with std::i/ostreams. Unfortunately, there's no
-// standard way to map between them, so we use the nonportable GNU stdio
-// extension fopencookie(), which creates a FILE* with custom read/write/seek
-// functions. BSD also has a similar function, funopen(), which we should
-// use too. Failing in all that, we should fall back on a tmpfile() buffer.
