/* 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. */
