Simple SimpleVFS project

Create a directory for your project. To have something for D:GameVFS to work with, create subdirectories main_data and user_data in the project directory. In these directories, create some random files or subdirectories. Create a file called main.d in your project directory. Paste the following code into the file:

>   import std.stdio;
   import std.typecons;
   import dgamevfs;

   void main()
   {
       // Two filesystem directories, one read-only and the other read-write.
       auto main = new FSDir("main", "main_data/", No.writable);
       auto user = new FSDir("user", "user_data/", Yes.writable);

       // Stack directory where "user" overrides "main".
       auto stack = new StackDir("root");
       stack.mount(main);
       stack.mount(user);

       // Iterate over all files recursively, printing their VFS paths.
       foreach(file; stack.files(Yes.deep))
       {
           writeln(file.path);
       }

       VFSFile file = stack.file("new_file.txt");
       // Creates "new_file" in "user" (which is on top of "main" in the stack).
       file.output.write(cast(const void[])"Hello World!");

       // Read what we've written.
       auto buffer = new char[file.bytes];
       file.input.read(cast(void[]) buffer);

       writeln(buffer);
   }

Code for this example can be found in the examples/getting_started directory.
