Torss - downloads selected torrents from RSS feeds

Question

I often have a problem with various private torrent trackers that by the time I add to torrent to my client it has already been active for a long time and I struggle to maintain a good ratio. As such I wanted something which could scrape the tracker's RSS feed, find torrents that match various patterns and download the torrent files to a folder for my torrent client to pick up.
So I wrote torss. It's quite simple, but it does what I need it to do. The user defines some rules, decides which "getter" to use (each RSS feed has its own getter) and runs torss with those settings (likely from cron).
Help:
$ torss -h
Usage: /usr/bin/torss -g getter [OPTIONS]...
torss is parser of RSS feeds which downloads files referenced in the RSS if the
title of the entry matches given rules.
-g, --getter getter script to use
-r, --rules rules file to use
-d, --destination destination path to save torrents to
-i, --history history file to use
-h, --help help
The rules file must contain an array named rules containing at least one entry.
These entries should be regular expressions (for grep -Ei) for torrent titles
to be downloaded. See /etc/torss/rules.sample
The getter script will be looked for in ~/.config/torss/getters/, then
/etc/torss/getters/ and finally as a file referenced from the CWD. This means
you can pass either simply the filename or the absolute/relative path.
The destination path will usually be a folder where your torrent client
automatically picks up torrent files.
The history file is used to ensure the same torrent isn't downloaded multiple
times, as such it should, for normal use, be left as the default value.
Example Use:
~/.config/torss/rules:
rules[0]="foobar S01E[0-9]{2}(.+)?720(.+)?x264"
Those rules match what's in a demo getter script that's included in torss.
$ torss -g demo
Downloading 'Foobar S01E02 720p x264-Pirate' to /home/sid
Downloading 'Foobar S01E01 720p x264-Pirate' to /home/sid
There is also a history file to avoid downloading the same torrents a second time.
I've created the following PKGBUILD, but not yet put it in the AUR as I'd like some feedback first.

Since it's on github I know I could use git to clone the repo for the latest code, but I prefer using tags to state releases. This way things like aurcheck/yaourt/packer/etc know there has been an update.
Some private trackers (the ones I made for myself) are already included, though you'll need to edit them, setting the cookiejar values to those of your own cookies.
I would greatly appreciate feedback, this is the first non-trivial bash script I've written.

Yes - and the same here all of a sudden. Very annoying indeed. I really don't want to have to have another app. just to read my RSS feeds but is that going to be the solution? I'm sure this trouble started after I'd inadvertently erased messages instead of marking them all read. And it's only with two VersionTracker feeds too, not the others I get. VT have yet to respond to my request for ideas but if the y do, I'll post here again.
