Quirky, a sister project of Puppy Linux, is a Linux distribution built with a custom tool called Woof. The underlying infrastructure, such as boot-up and shut-down scripts, setup tools, hardware detection, desktop management, user interface, speed and general ease-of-use are common across all distributions built with Woof, but a specific build will have a different package selection and further customisation (even totally different binary packages). Quirky is developed by the founder of Puppy Linux and Woof to push the envelope a bit further, to explore some new ideas in the underlying infrastructure -- some of which may be radical or odd, hence the name Quirky.
As usual, Quirky has most applications that a user needs, "out of the box". This includes SeaMonkey, Abiword, Gnumeric, Planner, Xine, Osmo, NoteCase, Grisbi, mtPaint, InkscapeLite, Xsane, plus just about all required drivers and firmware. All of this in a remarkably small size! Regarding extra packages, not much yet, but we do plan to create more PETs
