I'd like to use the latest version but have ~zero experience building Java apps and there's ~zero documentation for how to go from an "svn co ..." to a working app.
Clearly great work has been done for 0.90.0 but then stopped just before making it usable for many.
Please make a release! ("Perfect is the enemy of good")
Please also try to get into the way of regular releases. Automate a little more each time and pretty soon it'll be easy.
Please also add sufficient docs to the ZGRViewer repo so that someone not familiar with java can simply "svn co ...; cd ...; build.sh" and have a working app.
