tkxxs 0.1.3

TKXXS provides a very simple and very easy to use GUI (graphical user interface) for Ruby; It gives you a persistent output window and popping up (modal) dialogs for input; For a screenshot, see: <tt>https://github.com/Axel2/tkxxs/blob/master/images/screenshot.png</tt>; I tested it on Windows, only; Got user report, that it works on Ubuntu, too. TKXXS shall: * improve the usability of little applications, which otherwise would use a command line interface (CLI); for example by a GUI-file chooser * give a simple GUI front-end for apps, which take parameters on the command line. (stdout can easily be redirected to the OutputWindow.) * take only little more effort and coding time over programming a CLI; * be able to easily upgrade existing CLI-applications; * be comfortable in use (e.g. provide incremental search, tool-tip-help, ...); * be easy to install. Drawbacks: * I'v tested it only on Windows, but got user report, that it works on Ubuntu, too.l * For sure some more drawbacks which I'm not aware of now. TKXXS uses TK (easy to install).
