Along the lines of running Octave in a debugger, attached is a trivial  
patch so that people who are new to compiling octave know how to use  
run-octave.  It may sound kindof dumb, but it was a long time before I  
even knew that run-octave could start an "un-installed" build of  
Octave in the debugger.  Also, is there a logical place in  
documentation or a README to simply make mention of the run-octave  
script?
