Package: org.apache.groovy.groovysh

## [Groovy] Class Main

- org.apache.groovy.groovysh.Main

-     class Main
      extends Object

  A Main instance has a Groovysh member representing the shell, and a startGroovysh() method to run an interactive shell. Subclasses should preferably extend createIO() or configure the shell via getShell prior to invoking startGroovysh. Clients may use configureAndStartGroovysh to provide the same CLI params but a different Groovysh implementation (implementing getIO() and run()). The class also has static utility methods to manipulate the static ansi state using the jAnsi library. Main CLI entry-point for `groovysh`.
