Good point.

Right. Generally speaking, it built like a charm, very impressive. There is
other small gotcha. I used the .deb packages sun-j2se5.0-jdk-binary and
sun-j2se5.0-jre-binary which may do things differently from other JRE/JDK. In
any event JGR came with 
  /usr/lib/j2se5.0-sun//bin/java -cp JGR.jar:. -Xmx512m org.rosuda.JGR.JGR $*
but the path ought to be /usr/lib/j2se5.0-sun/jre/bin/java (with an added
jre).  Not sure if this is worth worrying about.

Can you let R's code from help.start() do the work for you?  Would be cleaner
than trying to guess where the scripts are hiding. And to Brian's point, they
shouldn't get called directly in the first place...


Hell, there are no rules here - we're trying to accomplish something.
