 The first time a channel is found in the config, the most recent videos returned by the youtube RSS endpoint are mirrored, and a new entry is added to channels_timestamps.csv with the timestamp of the last video. Subsequently each channel is checked for an entry in channels_timestamps.csv and only videos later than the last timestamp for the channel's entry are mirrored. The tool decides if it is the first time a channel is found based on whether it has an entry in channels_timestamps.csv. It is designed this way so that the tool can be stopped and restarted without attempting to upload duplicate videos when restarted.
 
 After that, the tool polls all channels in config.toml periodically based on the parameter <poll_frequency> which is in minutes, and mirrors all new videos for each channel as they are found.
