-------------
Copied the files equiv.sml and useful.sml from
library/real/theories/src

11.20:
------
Desided to stop and wait for Konrad. Problems: Can't make head and
tail out of useful.sml and Equiv.sml does not compile: contains lots of
small errors.

15.15:
------
Starting again.  Got some advice from Konrad:
	* load_library* X_lib => 
		load "XLib" (* ie. not necessary when sep comp. *)
	* Add_to_sml.add_theory_to_sml "s" =>
		open sTheory

useful ported: The "standart header" (taken from std.prelude) is inserted:
------------------------------------------
open Globals Exception Lib Parse;
open Term Dsyntax Thm Theory Drule 
     Conv Tactical Tactic Rewrite Thm_cont Resolve ;
open Const_def Const_spec Type_def Prim_rec Type_def_support;

infix THEN THENL THENC ORELSE ORELSEC THEN_TCL ORELSE_TCL ## |->;
------------------------------------------
here Psyntax is very important.
Also "open Compat" has been changed to "open hol88Lib".  A somehow
arbitrary signature has also been produced, using verbose := true.

Equiv ported: No real problems after inserting the "standart header"
and opening hol88Lib, boolTheory, and useful.

141097:
-------
the porting of int.sml started by adding:
open useful Equiv hol88Lib decisionLib Psyntax arithmeticTheory prim_recTheory
     numTheory;
notice that Psyntax has been opened again after hol88Lib(?)

Problem loading simplifier.

151097:
-------
Porting of int.sml continued.  Noticed that when ever '*' no nice
automatic tools.

161097:
-------
Porting of int.sml continued.  Some technical difficulties has araised:
Have changed:
	val int_tybij = definition "-" "int_tybij";
to
	val int_tybij = definition "int_tybij";
But Konrad was not around to confirm, that it was correct.
