At the moment, not much is the haps.

1. terminal output
  make

  ./main structs/smile.txt start

2. bitmap generator
  make tools

  tools/tobmp structs/smile.txt 8

3. SDL frontend
  make sdl
  ./sdl structs/smile.txt start

  space/enter - regen+link structures
  Z           - regen structures
  X           - link structures
  Q           - quit

  NOTE: for building on win32, you will need to copy SDL.dll (1.2) to the same directory as the Makefile before compiling.

Current structures:

  castle.txt
  small_town.txt
  ravine.txt
  tower.txt
  towers.txt
  holy_tower.txt
  smile.txt
