Fleet is an extension and library for the JTcl Interpreter that enables simple concurrent programming. A fleet contains one or more interpreters (members), each running in a separate thread. Communication to the fleet members is done via the fleetName tell command, passing a script to evaluate. Results of the fleet members' script evaluation is communicated back to the main interpreter by updating a variable, or by invoking a procedure, with a dict that contains the status and results of the evaluation.
Fleet is new beginning with JTcl 2.3.0, and is subject to change. For more information, see the fleet man page at: http://jtcl.kenai.com/docs/jtcllib/fleet.html
