Hi Thure. You are going to have to solve the same problem when you install
GCG 8.1. How do you plan to handle the multiple versions of srsbuild
and the programs?

That alone makes it desirable to run with the real SRS indices.

What does LookUp do that SRS can't? Did they change the output format
somehow?
How closely coupled are GCG and SRS? Can Lookup simply use standard
SRS indices (with SRS prepared), or does it need source editing and a
rebuild of LookUp?

So GCG has to run from a separate index directory if a site has any
database defined in SRS as a "Sequence" database but not in GCG format,
NRSUB at the EBI for example (at the Sanger Centre it just happens to have
moved to "Genome" along with other databases). Or have I misunderstood?
Presumably then GCG's LookUp is picking up "/group=@SEQUENCE_LIBS"
*only* and is not checking the sequence format? Or is it able to skip
databases in EMBL flatfile format (for example)?
This seems to imply needing either a completely separate set of indices
for GCG, or a lot of playing around with symbolic links (on Unix).
