Perhaps three command-line options to dbconcat for overriding the title, units, and color table. Checkboxes could be presented on the GUI whether to override or not, defaulting to not override so we match current behavior. > This seems entirely reasonable when > the import is actually concating into an existing db that already has > stuff in it. But if we are importing into an empty db (i.e., title == > "Untitled BRL-CAD Database", units == "mm", no color table, and no other > object in the db), perhaps we should also import the _GLOBAL object > attributes.

Seems reasonable to me to auto-import the settings without user prompting if _GLOBAL is in some canonical default form. Otherwise, though, I would think we'd want to treat those three features independently. It's merely a storage implementation detail that we stash them as attributes on the _GLOBAL object. I could see wanting to import a color table and units but not the title, for example. Cheers!
