Q: Does BitTorrent support resuming?
11
A: Yes, just save your download to the same location as the existing partial download.
12
BT will resume where it left off after checking the partial download.
15
Q: How do I know the download isn't corrupted?
17
A: BitTorrent does cryptographic hashing (SHA1) of all data. When you see "Download

A: BT allows you to control how many simultaneous connections can actively
49
download simultaneously using --max_uploads in the btdownloadheadless.py
50
script. Other than that you'll have to limit bandwidth some other way, perhaps
51
at the OS or router level.
