SYNOPSIS
========

alfsum **file** [**file** ...]

DESCRIPTION
===========

**alfsum** calculates the checksums used by the **ALF** compression
utility on the Atari 8-bit platform.

There are no options. Use **-** to read from standard input. Use
**./-file** to read a file whose name begins with **-**.

NOTES
=====

The checksum algorithm is very simple: all the bytes in the file are
added together, and the low 16 bits of the result are the checksum.

EXIT STATUS
===========

0
  Success.

1 to 254
  File I/O error count. If there are more than 254 I/O errors, 254 is returned.

255
  Error in command-line arguments.
