The All-Tcl (all-sining, all-dancing) SurfIt! Web browser.
		Version 0.3alpha

SurfIt! is a new World Wide Web browser implemented entirely 
using the Tcl/Tk language and toolkit.  I have uploaded it to 
ftp.aud.alcatel.com:/tcl/incoming, but in the meantime you can 
also get it from pastime.anu.edu.au:/pub/SurfIt/surfit-0.3.tar.gz

This initial public release is ALPHA quality, mainly since there 
is much work to do in defining the applet/hypertool APIs.  
It is being released in this form to get some feedback from the 
Tcl/WWW community.  I intend to do alot of cleaning up of the
distribution in later releases to make it easier to install and 
run the browser.  Given that there is no C code involved, it 
should run on any platform that supports Tcl/Tk, and should be
easy to port to the Mac & Windows versions of Tcl/Tk when they
become available from Sun Labs.

The browser is based upon Stephen Uhler's (infamous :-) Tcl HTML 
parser, which will parse HTML v1.0 and some HTML v2.0 elements.  
I have enhanced this with a subset of HTML v3.0 tables.  
The goal is for the parser to eventually be completely HTML v3.0 
compliant.  Given that Tcl allows rapid prototyping I expect to be
able to quickly add support for draft standards as they emerge
(once I've caught up with the current standards ;-)
SurfIt! also handles inline GIF, PPM and X bitmap images.

The most interesting aspect of SurfIt! is that it will download 
and execute Tcl scripts (aka "Applets").  SurfIt! uses Jacob Levy's 
Safe-Tcl extension (v0.2) to ensure that foreign, untrusted scripts 
cannot compromise the security of the computer that the browser 
is running on.

Some demonstration applets may be found at:

I am also very interested in developing a suite of hypertools.  
I'm currently working on the Plateau Multimedia Group's cmplayer 
application.  Others will include exmh and nn-tk.
