Runabouts were a popular car body style at the beginning of the 20th Century. They were small, inexpensive, open cars. Most runabouts had just a single row of seats, providing seating for two passengers.
Small starship used as courier, transport and scout. Contrary to popular belief, runabouts are never assigned as auxiliary vessels on larger starships, although they may be transported to remote bases by starships.
The Runabout is an extension of the Java libraries that adds two-argument multi-dispatch to Java without changing the language or the VM. It uses reflection to find visit methods, which are invoked using dynamically generated and loaded code. The Runabout does not need a special compiler or changes to Java's syntax.
