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