[ableasby at hgmp.mrc.ac.uk]

This is a bugfix release. The ChangeLog appears below. As usual, all
errors are added to the quality control suite to ensure they don't
recur.

Version 2.3.1

        est2genome fixed for large alignments (over 40Mbase for
        est * genomic sequence length)
        sequence reading for ABI files fixed (and selex files tested)
        genbank feature input working
        pepinfo PNG output larger to make the text readable (only affects
        PNG output)
	empty sequence file input fails gracefully
	empty sequence input fails gracefully (and only needs one
	^D from stdin)
