wip/eor 1.0.2 NetBSD

This program takes a set of files and generates a redundant file using the exclusive or bit operation. Later, if any of the original files happens to be lost or damaged, we can use the redundant file as a wildcard and regenerate the lost file again. This process is similar to what RAID-5 does to protect data on disk arrays.

The primary purpose of this tool is to protect author's photo archive stored on a set of DVDs (which are not 100% reliable), but the program use is actually universal.
