-    Unlike other object file formats, where the debugging information format
-    is implied by the object file format, the ELF object file format and the
-    DWARF debugging information format are two distinct, and potentially
-    separate entities.  I.E. it is perfectly possible to have ELF objects
-    with debugging formats other than DWARF.  And it is conceivable that the
-    DWARF debugging format might be used with another object file format,
-    like COFF, by simply using COFF's custom section feature.
-
-    GDB, and to a lesser extent BFD, should support the notion of separate
-    object file formats and debugging information formats.  For now, we just
-    use "elf" in the same sense as "a.out" or "coff", to imply both the ELF
-    object file format and the DWARF debugging format. */
