  22
  23 This file is generated from various .c files, if you change it, your
  24 bits may be lost.
  25
  26 All the prototypes and definitions following the comment "THE FOLLOWING
  27 IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
  28 BFD.  If you change it, someone oneday will extract it from the source
  29 again, and your changes will be lost.  To save yourself from this bind,
  30 change the definitions in the source in the bfd directory.  Type "make
  31 docs" and then "make headers" in that directory, and magically this file
  32 will change to reflect your changes.
  33
  34 If you don't have the tools to perform the extraction, then you are
  35 safe from someone on your system trampling over your header files.
  36 You should still maintain the equivalence between the source and this
  37 file though; every change you make to the .c file should be reflected
  38 here.  */
