Dear R subscribees, First, I am new to R and I apologize if the question is naive. I am trying to find out where arguments specifications can be found.

Everything works fine on my development box (Ubuntu 7.10, Ruby 1.8.6) but on my server (Fedora Core 6, Ruby 1.8.5) when I run script/backgroundrb start, the process fails to start.

I can''t figure any other reason it would fail...
