Please note that Flashout is not open source. It has been popularized as part of the FAME or FAMES = FAME + Swfmill solution. It currently scratches an itch but there is currently a completely open-source project underway to replace FAMES = FAME + Swfmill called Flames IDE. Once this open-source alternative to Flashout is ready, we will be removing Flashout from the site (unless it is open-sourced before that time, of course.)
Flashout plugin for Eclipse is a part of FAME solution and supplements ASDT + MTASC pair. Flashout allows viewing compiled SWF file directly in Eclipse platform. Also, it implements debugging facilities provided with several levels of debugging messages (with coloring) directly in the Eclipse platform.
Flashout developed and supported by Eugene Potapenko.
