jProbe is a viewer for Spice simulation output files ("rawfiles"), written in java. Its main characteristics are:

There is still no documentation - but jProbe should be rather self-instructing. And it does not have so many knobs and buttons yet.
The jProbe software is shipped as a tarball for Linux/Unix or a zip file for Windows. They contain the jProbe.jar executable and startup scripts. The difference between the two is - except the package format - only the startup script.
Changes between versions are described in the changeLog.
