111 /**
112 * A complete dynamic plugin manager system. This will allow you to design
113 * and use plugins that are compiled into your program and dynamically
114 * linked to your program interchangably. It works on windows and on *nix
115 * and bsd type systems (anything that supports dlopen). Basically you
116 * create a base class that will be the basic interface of your plugins.
117 * Then you create some classes that inherit from it, and use the
118 * PluginInterface3 macro to create the required data structures for it.
119 *
120 * Once you have plugins you can create a Plugger, by passing in the base
121 * class as it's template parameter. Once it's created, you can register
122 * plugins. To register a plugin that is builtin, you just need to pass
123 * a pointer to it's interface structure to the registerBuiltinPlugin
124 * function. To register a plugin that is in a shared object or dll file
125 * you just pass the filename (with path, probably), and the name of the
126 * structure to load and you're all set.
127 *
128 * To instantiate an object from a plugin simply call instantiate with the
129 * name of the plugin as specified in the interface macro. To destroy an
130 * object crated with the plugger do not delete it, instead pass it into
131 * Plugger's destroy function.
132 *
133 * Any objects not destroyed when the plugger is deleted will be destroyed
134 * automatically.
135 *
136 * It is important to note that some systems (linux at least) partition off
137 * the memory allocated by objects linked in at run time into a seperate
138 * segment that, while it can be accessed by the main program, cannot be
139 * safely or reliably freed by the main program. With that in mind it is
140 * a good idea to free all memory allocated by a plugin object in the plugin
141 * object and not allow the calling program to delete it.
