Description
===========
  "shapng" is a tool to convert a sha256-sum, gained from a string or file,
  into a 16x16 png-image. This image can be read visualy by mobile phones
  or other robots.

  How does it work
  ----------------
  First, a sha256-sum is generated from the input. Then, this sum is converted
  into a array of 256 bits and converted more into a 16x16 bit-box. The first
  bit is assigned to the top-left and the last to the right-bottom.

  It it READ horizontaly, from left to right and line by line.

Requirements
============
  - MorphOS 1.x

Installation
