A tutorial introduction to Swarm: Swarm as a platform for agent-based modeling

Interface vs. implementation

Main reasons for using tool(s) like Swarm:

Bottom line:

at some point the details (the implementation) stops being relevant provided the goal (the interface) is accomplished.

Separation of interface from implementation is accomplished by packaging Swarm code into a library.
library: a technical term for the packaging to provide users. a set of features in a given language environment and platform. It consists of:
- Implementation: the `clock work' [Details of what qualifies as a library varies from language to language]
- Interface: the information about how to use the clock, e.g. the presence of a winder, a hour, minute, and second hand (often called an API).
Currently, the Swarm library is available in: Java, Objective C, and Scheme. (More languages are pending.)
