the class OtpsEntryPoint method fromArgs.

/**
 * Create an OTP scripting entry point using the same command-line parameters as used by the OTP
 * application. This is useful when using scripting from an outside environment, using OTP as a
 * library. For example in jython the following script 'myscript.py':
 *
 * <pre>
 *   #!/usr/bin/jython
 *   from org.opentripplanner.scripting.api import OtpsEntryPoint
 *   otp = OtpsEntryPoint.fromArgs([ "-g", "." ])
 *   ...
 * </pre>
 *
 * One can then run jython with:
 *
 * <pre>
 *   CLASSPATH=otp.jar jython myscript.py
 * </pre>
 *
 * @param args Command-line arguments, as used by the application.
 * @return The "otp" scripting facade bean.
 * @throws Exception
