Kayne Ruse 43dadcdbb8 Rearrenged the directory tree
I just _had_ to get rid of that horrible libs/ directory. Now most of the
graphical stuff is in client/, but I'll create more subdirectories so that
they're not getting in the way.

Kayne Ruse 3f2fcdf9e1 Players are being added in the client
The client sends a debug player to the server, with a constant movement to
show that the new client _is_ connecting. The next thing to add is the
sync system, so that the clients know what the server looks like when they
first join.

Tortuga is a 3/4 top down multiplayer RPG set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer competition, exploration in an open world, and solo adventuring. The game runs on a Minecraft like server system with a goal of about 50-100 players on a single server. The player characters are tied to the server where they are created, and are susceptible to permadeath: deletion of a character upon death. The servers are designed to allow a large amount of modification by the hosts.
Tortuga is a 2D multiplayer role playing game set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer cooperation, competition, and server customization. The game runs on highly customizable server software that can support up to 150 simultaneous players or more. The player characters are tied to the server where they are created and are susceptible to permadeath: deletion of a character upon death.
## Libraries
## Dependencies
* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension, slightly modified. This must be installed first.
* [Codebase](https://github.com/Ratstail91/Codebase) - generic reusable code modules
* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
## Instructions
* This project uses C++11, which is available via GNU (or MinGW) 4.7, or Visual Studio 2012. Personally, I'm using MinGW 4.7.2.
* I'm trying to keep this as IDE agnostic as possible, so if you use an IDE, please add it's files to .gitignore.
* You can read more details on the GitHub wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
