252b5132
RH
27
28The bfd.h file is generated from bfd-in.h and various .c files; if you
29change it, your changes will probably be lost.
30
31All the prototypes and definitions following the comment "THE FOLLOWING
32IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
33BFD. If you change it, someone oneday will extract it from the source
34again, and your changes will be lost. To save yourself from this bind,
35change the definitions in the source in the bfd directory. Type "make
36docs" and then "make headers" in that directory, and magically this file
37will change to reflect your changes.
38
39If you don't have the tools to perform the extraction, then you are
40safe from someone on your system trampling over your header files.
41You should still maintain the equivalence between the source and this
42file though; every change you make to the .c file should be reflected
43here. */
