[Research] Using the .fds file format

[Paul Komarek]

By "junk", do you mean the funny-looking stuff after the header?  That
stuff (probably) isn't junk.  It is the compressed file format that
puts the "fast" in fds.

64 bit should not be a problem with fds code, nor should endianness if
I recall correctly.  Intel and Alpha machines had different word size
and endianness, but we were (I believe) using fds on both a long time
ago.  I'm not sure if the fds file from one worked on the other, but I
think it at least worked to save and load fds on a 32 or 64 bit little
or big endian machine.
