+Rediqueuelous is a stupidly simple Python queueing system. + +To make a task happen, simply lpush a string in the format +"module.function" or "module.function:args", where "args" is a +JSON-encoded dictionary, into the queue called "rediqueue" in your +Redis installation. Rediqueuelous will then call the method +"function" in "module" with "args" passed in as keyword arguments. + +How does Rediqueuelous know where to look for modules? Easy: there's +a hash key called "rediqueue.modules" which maps module names to paths +on the file system. So, for example, if I had a file /foo/printer.py +that I wanted to use in Rediqueuelous, I might issue + + HSET rediqueue.modules printer /foo/printer.py + +at which point I could lpush "printer.whatever" into "rediqueue" and +Rediqueuelous will do the right thing. + +There is a built-in module, called "rediqueuelous", which you can use +to control Rediqueuelous itself. It currently supports two functions: +"quit", which takes no arguments and quits Rediqueuelous, and +"tea_time", which takes a mod=modulename pair, and will load or reload +modulename. This allows you to redefine functions in Rediqueuelous +without restarting the server.
