wxWindows 2.3.3
---------------

*** Please note that this is an UNSTABLE DEVELOPMENT SNAPSHOT.
*** Unless you need the new features and bug fixes, you may wish to
*** use the official 2.2.x stable series.

Welcome to wxWindows 2, a sophisticated cross-platform C++
framework for writing advanced GUI applications using (where
possible) the native controls.

In addition to common and advanced GUI facilities such as
frames, scrolling windows, toolbars, tree controls, icons,
device contexts, printing, splitter windows and so on, there are
wrappers for common file operations, and facilities for writing
TCP/IP applications, thread handling, and more. Where certain
features are not available on a platform, such as MDI and tree
controls on Unix, they are emulated.

A detailed 1700-page reference manual is supplied in HTML, PDF
and Windows Help form: see the docs hierarchy.

For a quick start, point your Web browser at docs/html/index.htm
for a list of important documents and samples.

Installation
------------

wxWindows 2 needs to be compiled before you can test out
the samples or write your own applications.
For installation information, please see the install.txt file
in the individual directories:

  docs/msw
  docs/gtk
  docs/motif
  docs/mac
  docs/x11
  docs/mgl

Licence information
-------------------

For licensing information, please see the files:

  docs/preamble.txt
  docs/licence.txt
  docs/licendoc.txt
  docs/gpl.txt
  docs/lgpl.txt

Although this may seem complex, it is there to allow authors of
proprietary/commercial applications to use wxWindows in
addition to those writing GPL'ed applications. In summary,
the licence is LGPL plus a clause allowing unrestricted
distribution of application binaries. To answer a FAQ, you
don't have to distribute any source if you wish to write
commercial applications using wxWindows. 

However, if you distribute wxGTK or wxMotif (with Lesstif) version
of your application, don't forget that it is linked against
GTK+ (or Lesstif) which is covered by LGPL *without* exception
notice. Under Linux systems your app is probably linked
against LGPL glibc as well. Please read carefuly LGPL, section 6.
which describes conditions for distribution of closed source applications
linked against LGPL library. Basically you should link dynamicaly and
include source code of LGPL libraries with your product (unless it is
already present in user's system - like glibc usually is).
If compiled with --enable-odbc (Unix only), wxWindows library will 
contain iODBC library which is covered by LGPL.

If you use TIFF image handler, please see src/tiff/COPYRIGHT
for libtiff license details.

If you use JPEG image handler, documentation for your program should
contain following sentence: "This software is based in part on the work of
the Independent JPEG Group". See src/jpeg/README for details.

If you use wxRegEx class on a system without native regular expressions
support (i.e. MS Windows), see src/regex/COPYRIGHT file for Henry Spencer's
regular expression library copyright.
