- 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. */
