The All-Tcl (all-singing, all-dancing) SurfIt! Web browser.
			Version 0.4alpha

SurfIt! is a WWW browser implemented entirely using the Tcl/Tk language and toolkit.
It currently parses HTML v1.0, v2.0 and some HTML v3.0 elements.  
The goal is for the parser to be completely HTML v3.0 compliant and to support
stylesheets.  It 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 Safe-Tcl to ensure that foreign, untrusted scripts
cannot compromise the security of the computer that the browser is running on.

INSTALLATION
============

SurfIt! itself requires no compilation.  However, you need to have Tcl 7.5a2 and 
Tk 4.1a2 installed.  SurfIt! will run without any other extensions, but
Extended Tcl (tclX7.5a-a2) is required for the HTTP protocol handler and BLT 1.8
is necessary for HTML 3.0 tables (if you have SpecTcl 0.1a you could use its
implementation of blt_table).

Note that the use of the various extensions is quite basic, and so should be
upward-compatible.  If there is a newer version of an extension available 
then by all means use it!

See the included documentation for further installation instructions.
To run SurfIt! you need to have wish4.1 in your path, and then type `surfit'
