| /* bfd.h -- The only header file required by users of the bfd library |

| The bfd.h file is generated from bfd-in.h and various .c files; if you |
| change it, your changes will probably be lost. |
| |
| All the prototypes and definitions following the comment "THE FOLLOWING |
| IS EXTRACTED FROM THE SOURCE" are extracted from the source files for |
| BFD. If you change it, someone oneday will extract it from the source |
| again, and your changes will be lost. To save yourself from this bind, |
| change the definitions in the source in the bfd directory. Type "make |
| docs" and then "make headers" in that directory, and magically this file |
| will change to reflect your changes. |
| |
| If you don't have the tools to perform the extraction, then you are |
| safe from someone on your system trampling over your header files. |
| You should still maintain the equivalence between the source and this |
| file though; every change you make to the .c file should be reflected |
| here. */ |
