Backup a remote irc session's logdir to a local computer, move them to a local directory and then clean up any finished log files on the remote system.

The script assumes an irssi-like logdir setup using 'autolog_path = "~/irclogs/$tag/$0.%Y-%m-%d.log";'. It moves files from the remote directory into a similar directory structure locally. Once synced, the script removes all remote files bar the logfile for the current day (or, worst case scenario, the current day and the day before assuming a change of day mid-sync).

The script takes a very simple configuration file of the following format:

{
    "user": "my_remote_user",
    "host": "myirc.example.com",
    "backup_root": "/home/user/mybackups/",
    "second_dir_behaviour": "skip"
}

With user being the remote user, host being the remote host upon which the logs are stored, backup_root the local directory within which the files are to be stored, and second_dir_behaviour controlling the behaviour when the script encounters a network with a name that ends with a "2", which generally indicates a duplicate connection.
