SYNOPSIS
     jruby [  copyright] [  version] [ Sacdlnpswvy] [ 0[octal]] [ C directory] [ F pattern] [ I directory] [ K c] [ T[level]] [ e command] [ i[extension]]
           [ r library] [ x[directory]] [  ] [program_file] [argument ...]

DESCRIPTION
     Jruby is a 100% pure Java implementation of Ruby, an interpreted scripting language for quick and easy object oriented programming.  It has many features to
     process text files and to do system management tasks (as in Perl).  It is simple, straight forward, and extensible.

OPTIONS
     Ruby interpreter accepts following command line options (switches).  They are quite similar to those of perl(1).

       copyright    Prints the copyright notice.

       version      Prints the version of Ruby interpreter.

      0[octal]      (The digit  Äúzero Äù.)  Specifies the input record separator ($/) as an octal number. If no digit is given, the null character is taken as the sep Äê
                    arator.  Other switches may follow the digits.   00 turns Ruby into paragraph mode.   0777 makes Ruby read whole file at once as a single string
                    since there is no legal character with that value.

      C directory   Causes Ruby to switch to the directory.

      F pattern     Specifies input field separator ($;).

      I directory   Used to tell Ruby where to load the library scripts.  Directory path will be added to the load path variable ($:).

      K kcode       Specifies KANJI (Japanese) encoding.

      S             Makes Ruby use the PATH environment variable to search for script, unless if its name begins with a slash.  This is used to emulate
