Peg Solitaire is a board game played with pegs: in the classic mode, the board has 33 positions and 32 tokens because the center position is without form. The objective of Peg Solitaire is to remove the pegs but only with horizontal and vertical movements. It is also known as English peg solitaire or Senku. In the reverse modes, initially there is only one piece on the board.
GêBR is a simple graphical interface that facilitates geophysical data processing. While it is not a package for processing, it is designed to integrate a large variety of free processing packages. It can handle Projects and Lines, assemble and run processing sequences, and act as an interface to many freely-available seismic-processing packages (such as Seismic Unix, Madagascar, etc.)
