RDot — GraphViz diagrams for Ruby classes

Usage: rdot [options] <libs>

Note:
    --                               Stop options parsing, rest of line treated
                                       as <libs>.
                                     If it's a FIRST argument, the 'optparse'
                                       should not be loaded (include config
                                       files), no options will be parsed, all
                                       values will be default. And we can make
                                       graph of 'optparse'.
