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