Hi, Does anyone know of a good Linux alternative to Chairgun ( http://www.chairgun.com/), which is used with air riffles? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 -------------- next part -------------- An HTML attachment was scrubbed...
