The EGCG one included some files that were already generated by
scientists at EMBL but mainly (the files with the 3 letter names) from
the TRANSTERM database (maybe not an obvious place to look) now
available from ftp://ftp.ebi.ac.uk/pub/databases/transterm/

There is now a database generated from Genbank called CUTG which is
indexed on various SRS servers. File cutg.dat is in GCG format but all
in one file. SRS can extract the files for you, or you can use a
simple script to write individual files. There was one available from
http://www.seqnet.dl.ac.uk/srsdoc/getcutg but sadly SEQnet has moved
so the URL does not work any longer. There are over 7000 codon usage
tables in this database.

CUTG's home page is:
