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. */ | |
