| 25 | /* bfd.h -- The only header file required by users of the bfd library |
| 26 | |
| 27 | The bfd.h file is generated from bfd-in.h and various .c files; if you |
| 28 | change it, your changes will probably be lost. |
| 29 | |
| 30 | All the prototypes and definitions following the comment "THE FOLLOWING |
| 31 | IS EXTRACTED FROM THE SOURCE" are extracted from the source files for |
| 32 | BFD. If you change it, someone oneday will extract it from the source |
| 33 | again, and your changes will be lost. To save yourself from this bind, |
| 34 | change the definitions in the source in the bfd directory. Type "make |
| 35 | docs" and then "make headers" in that directory, and magically this file |
| 36 | will change to reflect your changes. |
| 37 | |
| 38 | If you don't have the tools to perform the extraction, then you are |
| 39 | safe from someone on your system trampling over your header files. |
| 40 | You should still maintain the equivalence between the source and this |
| 41 | file though; every change you make to the .c file should be reflected |
| 42 | here. */ |
