At the block name prompt, *NAME inserts the block's objects: after the
insertion point INSERT asks one scale factor and the rotation, and no
attribute values. A path (C:\parts\bolt.dxf), NAME=path or NAME= reads
the drawing through the io hooks and defines a block named after the
file (or NAME) from its model space, with the file's $INSBASE as the
base point, adding the layers, linetypes, styles and blocks it needs and
keeping this drawing's definitions. A plain path whose block already
exists asks whether to redefine it; NAME=path redefines without asking.
A file that can't be read is reported at the name prompt. The JSON form
takes `file` (optional `name`) and "*NAME".
