[5039]2 * @file resource_manager.h
[4836]3  *  The Resource Manager checks if a file/resource is loaded.
[3329]4
[4597]5    If a file/resource was already loaded the resourceManager will
[3655]6    return a void pointer to the desired resource.
7    Otherwise it will instruct the coresponding resource-loader to load,
8    and receive a pointer to it.
[4534]9
10    it is possible to compile the resource Manager without some modules by
[4597]11    just adding the compile flag -D....
[4534]12    (NO_MODEL)

14    (NO_TEXT)
