+  //   It's used lower case as part of the data directory path.
+  //     So, if prefix is /usr/local, then the system data dir is /usr/local/share,
+  //     and this apps data dir is /usr/local/share/"domain".
+  //   It's used upper case as part of environment variables to override directory paths at run time.
+  //     So "DOMAIN"_PREFIX, "DOMAIN"_BIN_DIR, "DOMAIN"_LIB_DIR, "DOMAIN"_DATA_DIR, and "DOMAIN"_LOCALE_DIR

+The executables currently live in ...../SledjHamr.
+  Test executables stay in the src directory.
+Media and other data in SledjHamr/media (includes the test sim and Irrlicht examples).
+Libraries are in SledjHamr/libraries (including Irrlicht, lemon, and some sources).
+  Should move LumbrJack and Runnr sources to src, and probably lemon to.
+  Irrlicht is statically linked, so except for it's media, we don't need it at run time.
+    We could probably move the Irrlicht examples we actually use (all test data anyway) to Test sim.
+
+Builders should be able to -
+  put binaries in /usr/local/bin
+  put libraries - /usr/local/lib/SledjHamr
+  put media in /usr/local/share/SledjHamr
+If they don't, those things should be in the build directory, where they are now.
+  And looked up locally to allow moving it as one thing.
+
+User should be able to -
+  Run sims from where ever they like.
+  Write GuiLua modules that reference media that is where ever it is.
+    Normally media would come along with the module.
+    So on disk modules would include media in the same directory as the module.
+    In world modules would be in some object, and the media should be in that object to.
+    Client side modules from the net ... dunno yet.
+  Write their own skins, using their own media.
+
+SOOOO ...
+  build.lua should set -
+    PACKAGE_BIN_DIR     = SledjHamr
+    PACKAGE_LIB_DIR     = SledjHamr/libraries   (should rename this to lib)
+    PACKAGE_DATA_DIR    = SledjHamr/media
+    PACKAGE_LOCALE_DIR  = SledjHamr/locale      (doesn't exist yet)
+
+  install.lua should -                  (doesn't exist yet)
+    SledjHamr binaries  -> prefix .. '/bin'
+    SledjHamr/libraries -> prefix .. '/lib/SledjHamr'
+    SledjHamr/media     -> prefix .. '/share/SledjHamr/media'
+      This should not include data that could be changable, so maybe the test sim should move elsewhere?
+        LuaSL at least puts compiled scripts in the test sim.
+        Nails will eventually make changes to the test sim during testing.
+        For now, we don't care, there's no actual installing going on.
+    SledjHamr/locale    -> prefix .. '/share/SledjHamr/locale'
+
+  Some library function should call all the elm_app_compile_*_dir_set() functions.
+  They should be set as -D options only for that library.
+  elm_app_info_set() has to be called for each different elm_main(), so that might be tricky.
+  elm_app_*_dir_get() can then be called from anywhere, and will get the same results.
+  NOTE - this is Elm specific, so non GUI stuff like LuaSL can't use it.
+  Seems that non Elm examples all just use the PACKAGE_*_DIR type macros directly in strings.

 Irrlicht is flickering like crazy.  Hmm, might be Irrlicht's fault,
 mostly it flickers to black, but I've seen it flicker to the first frame
 of the GL demo.  On the other hand, it shows the Elm background usually.
