Does gst have example on ROE? If so, it will be very helpful for me.
And current gst alpha does have support seaside, does this alpha version
runs well on vista? My last experience with gst on windows vista was
not successful. I have gcc path problem and next linking error and others.
On xp, with older version, I did make some small app with gst.

Anyway, thank you for your help.

I think it is best to look at the testsuite.

GNU Smalltalk has support for SQLite in ROE.  When I have time I have in 
mind to backport at least the backend-independence parts to Squeak.
