> This tool is useful if your DFS has problems due to a corrupted edit log. You can convert the binary "edits" file into a well-formatted text file, make any corrections to edit commands that you think are likely to fix the problem, and then convert the text file back to a binary "edits" file.
> NOTE: obviously if you are not careful you can damage your DFS beyond any hope of repair.
