The current readseq will not do feature table parsing nor
the requested ORF cutting and pasting. It doesnt' have any
particular file or sequence size limit, so it probably will
convert from genbank to fasta formats okay for large sequences.
I am working on a new version of readseq in conjuntion with a
new SeqPup. It will likely come in C++ and Java source, but not
C source. I've no idea when this updated readseq may be available.
