# Deluge Library, previously known as python-libtorrent:
#
# Deluge is a Python library for torrenting, that includes
# Deluge, which is Python code, and Deluge_core, which is also a Python
# module, but written in C++, and includes the libtorrent torrent library. Only
# Deluge should be visible, and only it should be imported, in the client.
# Deluge_core contains mainly libtorrent-interfacing code, and a few other things
# that make most sense to write at that level. Deluge contains all other
# torrent-system management: queueing, configuration management, persistent
# list of torrents, etc.
#
# Documentation:
# Torrents have 3 structures:
# 1. torrent_info - persistent data, like name, upload speed cap, etc.
# 2. core_torrent_state - transient state data from the core. This may take
# time to calculate, so we do if efficiently
# 3. supp_torrent_state - supplementary torrent data, from Deluge
