SHOW is a computer-based classroom presentation system based on the
idea of multi-level teaching materials. The basic idea is to produce
lecture notes, presentation material (to be shown to the students
during lecturing), and teacher's own directions from a single source.
SHOWS includes a program to produce the various versions as well as a
program to present the middle level material to the students. SHOW
uses plain ASCII files.

Features of the SHOW system include:

* abolition of slide paradigm
* discrimination of textual structures with colors during presentation
* text editing during presentation
* font and color configuration during presentation
* position marking and fast jumps during presentation
* textual search during presentation

SHOW is distributed as a zip-file. To install SHOW unzip the file and
obey instructions in the READ.ME file. To install SHOW on UNIX/Linux
you need a C compiler and Tcl/Tk and on Windows you need Tcl/Tk.

HTML-based SHOW is a variant of SHOW that relies on HTML editors for
preparing materials and HTML browsers for presentation and printing.
Thus HTML-based SHOW takes only care of creating the various versions
from the single source. 

As a result, HTML-based SHOW does not require Tcl/Tk, and on
DOS/Windows no C compiler is required either. On the other hand,
as a HTML browser is used for presentations, the special support of
standard SHOW for presentations is lost.

HTML-based SHOW is distributed as a zip-file. To install HTML-based
SHOW unzip the file and obey instructions in the READ_ME.FST file.
To use HTML-based SHOW you need an HTML browser.
