%% This module is a library of useful i/o functions. It is hoped that the
%% functions defined in it are basic enough to be used without modification
%% as components of more complex utilities.
%%
%% It is completely self-contained and uses no other modules. Its own
%% utilities are exported.
%%
%% Most of the code here is derived from the original prolog versions and
%% from similar code written by Joe Armstrong and myself.
%%
%% This module has been split into seperate modules:
%% io_lib        - basic write and utilities
%% io_lib_format - formatted output
%% io_lib_fread  - formatted input
%% io_lib_pretty - term prettyprinter
