Some detail (Brainstorm): This library will provide a simple way to create an application that can be: . A Server Application A server application usually starts when system boot, and then remain running as background process, don't matter who is currently logged. In Windows this will a "Windows Service" and in UNIX a "UNIX Daemon", and we can create a "Neutral Application" that is not a daemon and service, but uses "service interface" that will provide methods like an "init", "interrogate", "restart" and so on. Some type of "system global mutex" will be implemented in this flavor, then if user want, he can determine that only one instance of service will run in a system in same time. A web server, data base server and so on area examples. . A Usual Application A usual application is a normal application, that don't need all of features provided by "server application" usually is started by a user and run by a determined period. A command, mail client, MPI master/Slave and so on area examples. . Base Class Both classes will be derivated of environment class that will provide common thinks and proprieties like an "app path", "app name", "app work dir" and so on. For sample: A user that want create a server, extend your class of "server class" and then override methods that want to get needed behavior. // windows service, or daemon class myapp : public boost::application::server{}; // neutral server class myapp : public boost::application::server<neutral>{}; // usual application class myapp : public boost::application::app{}; Note that: 1) Application can be configured using Boost.Program_options 2) I want use Boost.Log to provide log functionality when available. 3) I want create a "service model" then I want use Boost.Extension to provide dynamically late bind extension (Pluf-in System). What Boosters think? This is useful or is fool lib? Boosters think that "this kind of lib" is very specific, and violate: "The library must be generally useful and not restricted to a narrow problem domain." or this kind of system is relevant to boost. Please let me know the correct way to follows! Please make suggestions! What more else? Thanks
