/*

A presentation of the tview package, implemented with tview.
|
|
|
|
Navigation
|
|
|
|
The presentation will advance to the next slide when the primitive demonstrated
|
|
in the current slide is left (usually by hitting Enter or Escape). Additionally,
|
|
the following shortcuts can be used:
|
|
|
|
- Ctrl-N: Jump to next slide
|
|
- Ctrl-P: Jump to previous slide
