252b5132
RH
28
29The bfd.h file is generated from bfd-in.h and various .c files; if you
30change it, your changes will probably be lost.
31
32All the prototypes and definitions following the comment "THE FOLLOWING
33IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
34BFD. If you change it, someone oneday will extract it from the source
35again, and your changes will be lost. To save yourself from this bind,
36change the definitions in the source in the bfd directory. Type "make
37docs" and then "make headers" in that directory, and magically this file
38will change to reflect your changes.
39
40If you don't have the tools to perform the extraction, then you are
41safe from someone on your system trampling over your header files.
42You should still maintain the equivalence between the source and this
43file though; every change you make to the .c file should be reflected
44here. */
