Sequence editor wanted

[Morten Andersen]

I'm looking for a free unix-based sequence editor like GCG's SeqEd.
It must minimally be able to:

 - read and write in at least one of the "officially blessed" formats: 
   (GCG,PIR,fasta,..), and 
 - treat the sequence and annotation separately

It would also be nice if one had the option of choosing between different
output formats, search for and translate ORFs, complement a DNA sequence,
toggle between RNA and DNA representations, etc. etc. 
GUI is not a requirement. 


Does such a programme exist?
