Subject Re: changing SequenceFile format

The next method has three version for three type of sequence file:
non-compression, record compression and block compression)
I think maybe you should write a new class for your data format rather
than modify SequenceFile, because it may be a bit complex for you  (it
has lots of features that you may not need)
