25/* bfd.h -- The only header file required by users of the bfd library
26
27The bfd.h file is generated from bfd-in.h and various .c files; if you
28change it, your changes will probably be lost.
29
30All the prototypes and definitions following the comment "THE FOLLOWING
31IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
32BFD. If you change it, someone oneday will extract it from the source
33again, and your changes will be lost. To save yourself from this bind,
34change the definitions in the source in the bfd directory. Type "make
35docs" and then "make headers" in that directory, and magically this file
36will change to reflect your changes.
37
38If you don't have the tools to perform the extraction, then you are
39safe from someone on your system trampling over your header files.
40You should still maintain the equivalence between the source and this
41file though; every change you make to the .c file should be reflected
42here. */
