How I use aria2 to download torrent files

I was reading topics' titles, and then I saw this one:
https://bbs.archlinux.org/viewtopic.php?id=154476
At first, he wanted to use aria2, but then he switched to rtorrent. rtorrent is great, but It's not good for scripting, so I don't use it. aria2 is the best way to download torrent files, within command line. But how?
I use this script, because sometimes aria2 stops downloading, but doesn't exit! It's not a big deal when you're near the computer, but when you go somewhere else, you can't check if it's downloading. So I wrote this little script:

#! /bin/bash

if [ ! -x /usr/bin/aria2c ]; then
    echo "aria2c is not installed"
    exit 1
fi

if [ ! -d ~/.torrentdl ]; then
    mkdir ~/.torrentdl
fi

while :; do
    for i in $@; do
        MAGNET=false
	if [[ "$i" = magnet* ]]; then
	    MAGNET=true
	elif [ ! -f "$i" ]; then
	    echo "The file ('$i') is not given or does not exist"
	    exit 1
	fi
	if ! aria2c --hash-check-only=true "$i" &> /dev/null; then
	    aria2c "$i"
	    sleep 30m && kill -9 `pidof aria2c`
	else
	    echo "Torrent is downloaded!"
	fi
    done
done

Simply, it starts downloading and restarts it every 30 minutes.

There are some arguments that will help you with aria2:

-S, --show-files[=true|false]:
Print file listing of ".torrent", ".meta4" and ".metalink" file and exit. In case of ".torrent" file, additional information (infohash, piece length, etc) is also printed.

--hash-check-only[=true|false]:
If true is given, after hash check using --check-integrity option, abort download whether or not download is complete.

Maybe this belongs in the wiki, specifically the "Useful Tips and Tricks" section. It is not vital to usage of aria2, but I am sure there are others that might find this useful, and the wiki seems like a much more logical place to go searching for something like this.
