DESCRIPTION

       Jython is an implementation of the high-level, dynamic, object-oriented
       language Python seamlessly integrated  with  the  Java  platform.   The
       predecessor to Jython, JPython, is certified as 100% Pure Java.

       Jython  is  complementary  to  Java  and  is  especially suited for the
       following tasks:

       Embedded scripting:
              Java programmers can add the Jython libraries to their system to
              allow  end users to write simple or complicated scripts that add
              functionality to the application.

       Interactive experimentation:
              Jython provides an interactive interpreter that can be  used  to
              interact  with  Java packages or with running Java applications.
              This allows programmers to experiment with and  debug  any  Java
              system using Jython.

       Rapid application development:
              Python  programs are typically 2-10X shorter than the equivalent
              Java program.  This translates directly to increased  programmer
              productivity.   The seamless interaction between Python and Java
              allows developers to freely mix the two  languages  both  during
              development and in shipping products.

       To  make  a  jython  script  executable  on your system you can add the
       following line to the top of the file:

              #!/usr/bin/env jython

       You will also need to add  execute  permissions  to  the  script  using
       chmod(1).   Note  that  #!/usr/bin/jython  will  not work; you must use
       #!/usr/bin/env jython.  This is because  /usr/bin/jython  is  a  script
       itself, not a compiled binary.

OPTIONS

       A summary of options is included below.

       -i     Continue  running  Jython  interactively after running the given
              script, and force prompts even if standard input doesn’t  appear
              to be a terminal.

       -S     Don’t imply import site on initialisation.

       -v     Trace import statements on error output.

       -Dproperty=value
              Set  the  Jython  property property to value; see jython.conf(5)
              for details of available properties.

       -Wargument
              Warning   control.   The    full    form    of    argument    is
              action:message:category:module:line.   Trailing empty fields may
              be omitted. Multiple -W options may be given.  See documentation
              of the warnings module for details.

       -Ecodec
              Set the encoding used to read module source files from disk.

       -Qargument
              Division  control.  See PEP 239 for details. Valid arguments are
              old, new, warn and warnall.

       -jar jar
              The program to run is read  from  the  file  __run__.py  in  the
              specified jar archive.

       -c cmd The  program  to  run  is passed as the cmd string.  This option
              terminates the options list.

       file   The program to run is the script file.

       -      The  program  to  run  is  read  from  standard  input  (default
              behaviour).  Interactive mode is used if running on a tty.  This
              flag allows you to pipe a  file  into  Jython  and  have  it  be
              treated correctly.

       script-args
              Command-line   arguments   to  pass  to  the  Jython  script  in
              sys.argv[1:].

       --help Print a usage message and exit.

       --version
              Print the Jython version number and exit.

ENVIRONMENT VARIABLES

       JAVA (default: /usr/bin/java)
              The Java interpreter to use when running Jython.

       JAVA_OPTIONS (default: empty)
              Options to pass to the Java interpreter when running Jython.
