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