Subsequent scans detect any files that were added, changed, or deleted. The class can also setup the database tables to perform the initial configuration.
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.

For the moment, it only provides a simple command line interface and a C library other programs can use to cover some basic needs for data sorting.
