   8 # Realism separates the code into three main pieces: UI, engine, and game/mod.
   9 # The ui used will be one of the modules in the ui subdirectory.  It handles all
  10 # direct interaction with the user.
  11 # The engine is stored in the engine subdirectory and consistes of all of the
  12 # generic code that doesn't deal directly with the game and its story, such as
  13 # the combat mechanics.  It also has virtual modules that load data from the
  14 # game and mod.
  15 # Everything that can be changed by a mod is stored in the main_game
  16 # subdirectory.  This includes monsters, spells, maps, and items.  Actual mods
  17 # can be put in a mods subdirectory of Realism's main directory, or in the
  18 # user's home directory (as explained below).

  20
  21 # We allow mods to exist in the user's home directory, path:
  22 # ~/.realism-rpg/mods/<modname>/
  23 # On Windows XP, this translates to:
  24 # <drive>:\Documents and Settings\<user>\.realism-rpg\mods\<modname>\
