This would be probably doable with some sort of black magic, but
it won't be very easy IMHO. Such as - if some very clever structure
of the translation table would be thought out, it could be possible
to mmap() the contents and access the memory as (sort of) array.
The only problem I can think of is that the the contents would need
to be byteswapped as appropriate, so that the file can be shared
between BE/LE systems.
