The Range is exclusive (defined with three dots) meaning that it does not include the end object in it's results. It could be made up of Integer, String, Time, or really any object that responds to #<=> and #succ. (which are the only ...

Hi, Is there any parameter to rdoc that tells it to include all unchanged files again, too? Calling rdoc a second (third, fourth) time, just parses the files that have been changed and index.html only shows the content of this parsed file. The other files are still available in the subdirectory but not shown. Might be an easy thing - ...
