GRALE is a set of tools - a library and a number of accompanying applications - to study gravitational lenses. Gravitational lenses are astronomical objects so massive that their gravitational pull even deflects light rays. This can cause multiple copies of the same background object to be visible, like a cosmic mirage. The locations and shapes of these copies can provide information about the mass distribution of the gravitational lens, which GRALE can help recover using a genetic algorithm-based method. Apart from these so-called lens inversions, it's also possible to simulate gravitational lenses.
Shellp is a shell helper library. It is intended to make it easier to write commandline-based applications. Commands are easy to define, and can be entered interactively or by reading from a file or standard input. If a graphical workspace is available, a Qt-based interface can be used. Otherwise, an ncurses-based one may be used. If the platform doesn't support that, either, reading from a file is still an option.
MyRad4PHP creates applications on the fly, making a Web application without writing a single line of code. It's inspired by the Entity Framework and Dynamic Data Web sites (Microsoft). The generated application can extend or write code to customize all or some of its functionality. This tool takes a MySQL database and creates a Web application in seconds.
