+==================
+WARNING: THIS SCRIPT IS STRICTLY FOR DFHACK DEVELOPERS.
+
+Running this script on a new DF version will NOT
+MAKE IT RUN CORRECTLY if any data structures
+changed, thus possibly leading to CRASHES AND/OR
+PERMANENT SAVE CORRUPTION.
+
+Finding the first few globals requires this script to be
+started immediately after loading the game, WITHOUT
+first loading a world. The rest expect a loaded save,
+not a fresh embark. Finding current_weather requires
+a special save previously processed with `devel/prepare-save`
+on a DF version with working dfhack.
 
---[[
+The script expects vanilla game configuration, without
+any custom tilesets or init file changes. Never unpause
+the game unless instructed. When done, quit the game
+without saving using 'die'.
 
 Arguments:
 
-    * global names to force finding them
-    * 'all' to force all globals
-    * 'nofeed' to block automated fake input searches
-    * 'nozoom' to disable neighboring object heuristics
