| 1 | +PYTHorrent |
| 2 | +========== |
| 3 | + |
| 4 | +This is a BitTorrent client written entirely in Python so that it can be |
| 5 | +easily used for experiments. It is a fully working BitTorrent client so |
| 6 | +you can use it below as an example. There is no intelligence in this |
| 7 | +such as getting rarest peice first. Everything is random. |
| 8 | + |
| 9 | +It doesn't use ``thread`` or ``multiprocessing`` as it's designed to be |
| 10 | +used for experiments, and I don't know how someone may want to use it, |
| 11 | +while also making it impractical for general use, but I'd like to |
| 12 | +eventually support the most common schemes such as DHT, Magnet URLs, PHE |
| 13 | +tDP, and UPnP so it is possible to accept incoming connections. |
