I suppose I should clarify how I thought this would work.   The extrapkg 
etc. scripts just loop over ${pkgname[*]}, and commit it to the "main" 
directory, being whatever the package puts it in.  The packager would 
need to make the symlinks for their other packages, much like we 
currently have to set up pkgname/{trunk,repo} for any new package.  Then 
there should not need to be any changes in the db-scripts (I think...).
