A Java application is a Java class with a special method
(whose name is main). The application can be invoked directly
by naming it in the Java command.
If you want to generate an application from a Scheme program,
create a Scheme source file with the definitions you need, plus
the top-level actions that you want the application to execute.
You can compile in the regular way decribed in the previous section, but add
the --main option. For example,
assuming your Scheme file is MyProgram.scm:
kawa --main -C MyProgram.scm
This will create a MyProgram.class which you can either load
(as decribed in the previous section), or invoke as an application:
java MyProgram [args]
Your Scheme program can access the command-line arguments args
by using the global variable ‘command-line-arguments’.
