1. I wasn't aware that cURL was a download manager (to replace AutoGet or VPowerGet), as the original poster wanted; rather, it looks like the core tool that could be used for the downloading function in a script - provided that you didn't want such things as resumability of partial downloads or accumulation of URLs for later downloading, which I assume that any competent download manager will support. Can you explain how cURL in isolation handles this?

2. I also wasn't aware that it was a way to find a file when the known sites for downloading said file have closed or otherwise no longer seem to host the file requested; could you explain how that's done? (This was my purpose in providing links to the Wayback Machine.)
