    It depends, really.  GNUstep uses libraries instead of frameworks,
because proper framework support on most platforms may be impossible, so
all of the libraries and their resources get put in the Libraries/
directory.  Libraries/ has a bundle structure, and library code can use
the NSBundle methods to find resources.  Therefore, like in frameworks,
resources that the library code expects to find should go in there.
    The Library/ directory, as best I can put it, is for resources the
library/program code *doesn't* expect to find.  That is, optional
resources that users and/or admins can extend in
$GNUSTEP_USER_ROOT/Library.  Resources the code will use if found, but
run fine without.
    However, DGS doesn't use Libraries/ as a bundle, and its init files
aren't option, so no spot is completely appropriate.

    As per the description above, Images/, NSCharacterSets/, and
NSTimeZones/ should stay put.  Images contains widget images needed by
gnustep-gui, NSCharacterSets/ contains files for the standard character
sets available through the NSCharacterSet API, and since it doesn't make
sense for users to add timezone files, the NSTimeZone class can keep
those resources to itself.  PrinterTypes/ needs to move, as NSPrinter
does not rely on them, and admins/users certainly need to add PPDs.
    The others are more problematic.  There's special handling for
"GNUstep DTDs" in the GSXML code, so maybe those should stay is
Libraries/, and another DTDs/ directory created in Library/?  With
DocTemplates/, I'm really not sure what's going on.  And for Languages/,
those files contain a property list of language defaults that
NSUserDefaults relies upon, but it would also be nice to allow
additional languages installed later. 

All persons, living or dead, are purely coincedental.
