I use my powerbook for almost all the work on OSM using the JOSM tool. But starting the Terminal.app, cd’ing into the right directory, typing the command,… is actually a pain in the ass (at least for me 
. Mac OS X is a nice operating system and therefore there should be a nice starter 
. So, i fired up Jar Bundler and IconCompser to build a .app.
I want to verify on the developer list if I’m allowed to bring it online.
Edit: here it is.
Edit2: as this is veeeery outdated, i pulled it. I’m not even using the powerbook anymore…
