======================================================================
               sha256 - calculate SHA-256 message digest
                            (by Thoronador)
======================================================================


Purpose of the programme:
=========================

The sha256 programme calculates and prints SHA-256 (256bit) checksums
of all files that are passed to it as command line parameters.
As of version 1.1 it can also be used to calculate SHA-1 (160bit)
checksums, if desired.


Programme call:
===============

Since this (obviously) is a command line programme, you can call it
via command line/ shell. A list of valid options follows below.


Synopsis:
---------

  sha256 [--sha1 | --sha256] FILENAME ...


Options + parameters:
---------------------

  --sha1
      Calculate SHA-1 (160bit) checksums instead of SHA-256.

  --sha256
      Calculate SHA-256 (256bit) checksums. This is the default.

  --help
      Show a help message and list valid programme options.

  --version
      Print version information and quit.

  FILENAME
        path to a file that should be hashed. Can be repeated
        multiple times.

A typical call could look like:

  sha256 foo.txt some_dir/bar.baz

This would calculate the SHA-256 message digests of foo.txt and
bar.baz in the subdirectory some_dir. If one of the given files does
not exist, the programme quits.
