@ -1063,10 +1063,77 @@ This is the typical way of creating a hook from C code.
Currently, the variable is created in the root module. This will
change when we get the new module system.
** The smob interface
The interface for creating smobs has changed. For documentation, see
data-rep.info (made from guile-core/doc/data-rep.texi).
*** Deprecated function: SCM scm_newsmob (scm_smobfuns *)
>>> This function will be removed in 1.3.4. <<<
It is replaced by:
*** Function: SCM scm_make_smob_type (const char *name, scm_sizet size)
This function adds a new smob type, named NAME, with instance size
SIZE to the system. The return value is a tag that is used in
creating instances of the type. If SIZE is 0, then no memory will
be allocated when instances of the smob are created, and nothing
will be freed by the default free function.
*** Function: void scm_set_smob_mark (long tc, SCM (*mark) (SCM))
This function sets the smob marking procedure for the smob type
specified by the tag TC. TC is the tag returned by
`scm_make_smob_type'.
*** Function: void scm_set_smob_free (long tc, SCM (*mark) (SCM))
This function sets the smob freeing procedure for the smob type
specified by the tag TC. TC is the tag returned by
`scm_make_smob_type'.
*** Function: void scm_set_smob_print (tc, print)
- Function: void scm_set_smob_print (long tc,
scm_sizet (*print) (SCM,
SCM,
scm_print_state *))
This function sets the smob printing procedure for the smob type
specified by the tag TC. TC is the tag returned by
`scm_make_smob_type'.
*** Function: void scm_set_smob_equalp (long tc, SCM (*equalp) (SCM, SCM))
This function sets the smob equality-testing predicate for the
smob type specified by the tag TC. TC is the tag returned by
`scm_make_smob_type'.
*** Macro: void SCM_NEWSMOB (SCM var, long tc, void *data)
Make VALUE contain a smob instance of the type with type code TC and
smob data DATA. VALUE must be previously declared as C type `SCM'.
*** Macro: fn_returns SCM_RETURN_NEWSMOB (long tc, void *data)
This macro expands to a block of code that creates a smob instance
of the type with type code TC and smob data DATA, and returns that
`SCM' value. It should be the last piece of code in a block.
** The interfaces for using I/O ports and implementing port types
(ptobs) have changed significantly. The new interface is based on
shared access to buffers and a new set of ptob procedures.
*** scm_newptob has been removed
It is replaced by:
*** Function: SCM scm_make_port_type (type_name, fill_buffer, write_flush)
- Function: SCM scm_make_port_type (char *type_name,
int (*fill_buffer) (SCM port),
void (*write_flush) (SCM port));
Similarly to the new smob interface, there is a set of function
setters by which the user can customize the behaviour of his port
type. See ports.h (scm_set_ptob_XXX).
** scm_strport_to_string: New function: creates a new string from
a string port's buffer.

ramap.c: serial-array-copy!, serial-array-map!
- remove module (ice-9 getopt-gnu-style)
- remove kw.h, scm_tc16_kw
- remove genio.h
- remove deprecated function scm_newsmob.
Modules sort.c and random.c should be factored out into separate
modules (but still be distributed with guile-core) when we get a new
