So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

{{{#!highlight powershell

$files = ls Level*.html
foreach ($item in $files) {
    (Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item
}
