We have an existing terrain database consisting of 1x1 degree square .osga 
files.  The database was created when osgdem still supported the -a option to 
compile everything into an archive file.  We are upgrading our application to 
run on OSG 2.8.2 and I would like to rebuild the terrain database with the 
newer version of VPB and the corresponding OSG.  Since I cannot create the 
.osga files with osgdem, I had tried to create the archive later with 
osgarchive.  However, I can only load the new .osga file properly, with 
osgviewer, if the output directory containing the .ive files still exists and 
has not been renamed.  If the directory has been removed, osgviewer will only 
display the master .ive file and does not seem to find the rest of the archived 
.ives.  Is there a workaround to this problem, or some other way to archive the 
.ives into an .osga file?

Thanks,
Kevin
