  -Cdirectory     cd to directory before executing your script
  -d, --debug     set debugging flags (set $DEBUG to true)

  -Eex[:in], --encoding=ex[:in]
                  specify the default external and internal character encodings
  -Fpattern       split() pattern for autosplit (-a)
  -i[extension]   edit ARGV files in place (make backup if extension supplied)
  -Idirectory     specify $LOAD_PATH directory (may be used more than once)
  -l              enable line ending processing
  -n              assume 'while gets(); ... end' loop around your script
  -p              assume loop like -n but print line also like sed
  -rlibrary       require the library before executing your script
  -s              enable some switch parsing for switches after script name
  -S              look for the script using PATH environment variable
  -v              print the version number, then turn on verbose mode
  -w              turn warnings on for your script
  -W[level=2|:category]
                  set warning level; 0=silence, 1=medium, 2=verbose
  -x[directory]   strip off text before #!ruby line and perhaps cd to directory
