Comment:

 Throwing this into needs_review myself.

 I'm not so sure that having this stuff in separate run-length and cc files
 will actually be needed; endianness issues will keep us from reading any
 portable file into an array-of-country verbatim, I think.  Let's see how
 tricky the read code is before we decide that complexifying the format is
 worth it in order to make the read code simpler.

 I'm also not clear how  best to read this format quickly on the fly:
 unpacking it all into ram seems like a lose if we don't have to; a
 workable index format would be neat (and would be much easier for fixed-
 length or self-synchronizing records.
