| **A dynamic extension language.** Buzz is a [[https://en.wikipedia.org/wiki/Dynamic_programming_language|dynamic language]] that allows one to express complex swarm behaviors with concise scripts. Buzz is designed as an //extension language//. The task of an extension language is to allow the programmer to work at a higher level of abstraction with respect to that of the underlying system. Thanks to its [[buzz_c_cpp|C interface]], Buzz can be used with any kind of robot software that can interoperate with C or C++. This makes it very simple to install Buzz on practically any existing robot, and also integrate it with frameworks such as [[http://www.ros.org/|Robot Operating System]]. | **A dynamic extension language.** Buzz is a [[https://en.wikipedia.org/wiki/Dynamic_programming_language|dynamic language]] that allows one to express complex swarm behaviors with concise scripts.

| | In principle, a Buzz script can be organized in any way one likes. Typically, however, a number of standard functions are present, because they need to be called by the underlying system to proceed with the execution. These functions take care of initialization, memory cleanup, reset, and stepping. To ensure standardization across different robots, it is considered standard to include into a Buzz script at least these four functions as shown below. |
