This code was moved from libferris/Ferris/SignalStreams and a few other
source files in libferris. The original code was Copyright (C) 2001 Ben Martin,
some minor changes have been made to this source release by Ben Martin and thus
files are marked with (C) 2001-2003.

This library contains some extensions to Standard C++ IOStreams. 
These extensions allow;

* additions for UNIX semantics. For example a file stream can be 
  created using o_mmap|o_mseq when one wants a memory mapped file
  to be used an madvise(2) that access to that area will be sequential.

* relative URL handling (passing "~/.myconf" to ifstream() will do the
  right thing).

* stream handles to be passed by value

* easy reference counting on streambuf objects

* closed signals to be fired when a streambuf is going to be
  deleted. see ut_close_signal.cpp for an example.

* A collection of IOStreams which complement the standard ones on offer
  see MakeMemoryIOStream(), MakeFdIOStream(), MakeHoleyOStream(),
      MakeLimitingIStream(), MakeProxyStream(), 
      fcin(), fcout(), fcerr()

* ferris_basic_streambuf<> base class for implementing custom streambuf subclasses
  This contains much of the boilerplate style code from "Standard C++ IOStreams
  and Locales" by Angelika Langer and Klaus Kreft. Also one_arg_manip<> from
  the above book

* XSLT style functions ends_with(), starts_with(), contains().

* additional stream manipulators nl, nlf etc.

* stream to string convertion functions for both stringstreams and istreams.

These were split out of the main libferris library so that other library
creators can use the streambuf class and pass-by-value iostream wrappers
in their APIs. For example libstldb4 uses this library to allow partial
retreival of data items using an iostream interface.

Its a win-win, if other libraries use this to give a nice iostream interface
then a libferris wrapper will be much easier to make for those other libraries
so I can make libferris more powerful by mounting more libraries as a filesystem.

Requires;
	glib 2.0+
	libsigc++ 1.0+
	ferrisloki 1.6.0+
