29 A BFD has type <<bfd>>; objects of this type are the
30 cornerstone of any application using BFD. Using BFD
31 consists of making references though the BFD and to data in the BFD.

34 contains the major data about the file and pointers
35 to the rest of the data.

653 they call <<bfd_set_error>> to set an error condition that callers
654 can check by calling <<bfd_get_error>>.
