dirq 1.1.2 documentation. Hey, I was recently looking for something like this - a queue based on the file system. The advantage: simplest persistence and good "debugging" by simply poking around in the file system. The disadvantage is that queues often need to perform some operations atomically - and this can become a bit tricky if you want to get it right. This is a port of an already existing Perl module, so the chances that most of the childhood diseases are out are quite high. The API, in any case, looks nicely simple. Definitely worth a closer look.
