I'm writing a specialized to-do list app. I'm using Django but this is

I've got pretty much everything in the app worked out, except
Does anyone know of any python based barcode readers? I'm looking for
something (commercial or open source) that will use some OCR algorithm
to read barcodes from an image or ps/pdf file, and ideally will be
something along the lines of a callable python script. I have some
pretty simple needs, i

I was asked by my employer to publish this a bit ago, so here it is:

It's a multithreaded script for running n POSIX shell commands m at a
time with good error checking. It allows for things like stashing in ssh
$hostname or rsync $hostname in

I also forgot to mention that it need not be nearly as robust as
something like Jailhelper 2.0, I will not really need to compensate
for noise and irregular conditions. All of my barcodes will be
scanned in a predictable, and consistent environment (i.e. a scanner),
so all i need is some stupid li
Great thanks
