Papiosaur has just made available a new version of its first graphical interface named JoinGUI created with the Hollywood programming language.
This interface uses the Join command included in MorphOS. The interface makes it easy to join multiple files in one. For the moment, iso, vob, mp3, png (DualPNG icon) and txt have been joined succesfully. Other formats are probably compatible but not tested. If you know of any, please let me know. The interface uses the Hollywood RapaGUI external module. Versions for AmigaOS3.x, AmigaOS 4.x as well as AROS should be availbale soon.
Others GUI are under study (file conversion, etc...). If you want small specifics projects, don't hesitate to contact me.
