+To rotate the scene 90 degrees about the Y-axis and scale by 10:
+.IP "" .2i
+robjutil -x "-ry 90 -s 10" orig.obj > transformed.obj
-+
+.SH NOTES
-+
+The .OBJ output of
-+
+.I robjutil
-+
+uses relative indices, so files it produces may be concatenated
-+
+on the input of other tools such as
-+
+.I obj2rad
-+
+and
-+
+.I obj2mesh
-+
+by piping from
-+
+.I cat(1)
-+
+or similar.
-+
+This offers a convenient way to separate geometry from a single .OBJ
-+
+input, manipulate it in some way, then recombine during conversion.
-+
+.PP
-+
+Unlike
-+
+.I obj2rad
-+
+and
-+
+.I obj2mesh,
-+
+.I robjutil
-+
+with the
-+
+.I +r
-+
+option will not substitute the group name for a material id if no
-+
+.I usemtl
-+
+statements are found on the input.
-+
+Instead, it will assign each surface the material
-+
+.I DEFAULT_MATERIAL.
-+
+Since it is possible to use the
-+
+.I +/-g
-+
+option to select groups to include or exclude on output, it is
-+
+still possible to assign materials by group manually.
