If you want to be able to run s2compile without installing a Java Development Kit (Big download. Probably waste of disk space if you never do Java development) you might be interested in my precompiled distribution, which only requires a Java Runtime Environment. (Still big download, but less big. Needed for running any Java app.)
Someone submitted syntax highlighting definitions for some text editor last time I mentioned this. I've not put them in the package yet, but will get to it eventually.
Updated S2View coming shortly.
