AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. It supports the following features: tunable webcam sampling; image stacking (averaging, additive etc.); pre and post-capture gamma (brightness) and contrast correction; dark-shot CCD calibration (subtractive); and an internal 16-bit grey-scale format for optimal resolution.
Perl modules are notated in many different formats: "Foo/Bar/Baz.pm", "Foo::Bar", "Foo-Bar", etc. Module-Format allows one to take a list of modules in any format (including mixed ones) and output it in a consistent format that can be input to an installation program or an information querier.
