I'm not going to provide the whole data dir as a tarball as you can
download these from the original sites much faster, so they will have size 0 in
the tarball. 
 
These include 
lib/ensembl.pep (ensembl confirmed protein set)
	ftp://ftp.ensembl.org/pub/current/data/fasta/pep/ensembl.pep.gz
problemdata/problem6/yeast.aa (yeast protein seqs)
	ftp://ftp.ncbi.nlm.nih.gov/pub/blast/db/yeast.aa.Z
problemdata/problem6/gbvrl1 (genbank virus division release)
	ftp://ftp.ncbi.nlm.nih.gov/genbank/gbvrl1.seq.gz
problemdata/project2/drosophila_mrna.ffn
	ftp://ftp.ncbi.nlm.nih.gov/genbank/genomes/D_melanogaster/Scaffolds/mRNA/mrna.fa
problemdata/project2/a_fulgidus_NC_000917.ffn (predicted ORFs)
