* Simple tutorial runner
  This tutorial runner can be used to make simple guides through [[https://ngn.codeberg.page/][ngn/k]] functionality.  It takes a
  script with executable code and comments and prints the code/comments line by line with lines
  being advanced by hitting return.

  If instead of return some code is typed by the user then that code is executed offering an
  opportunity for a more interactive experience.

* API
  When run from the command line, this simply takes a list scripts to be run.

* Sample run:

  : $ k tutorial.k ktour.txt
  :     1 + 1     / basic arithematic can be done with infix notation
  :   2
  : 
  :     5 * 7
  :   35
  : 
  :     2 - 4
  :   -2
  : 9-8    // <--- this is me typing, and then continuing
  : 1
  : 
  :     3 % 2     / division is done with % since / serves other purposes like the beginning of a comment!  :D
  :   1.5
