21 | /* bfd.h -- The only header file required by users of the bfd library | |
22 | ||
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. */ | |
