+* Runs as python script (loop by default to reduce disc reads since stores certain info) run like:
-    chunkymap-regen.py --loop true

-* Change program status while looping by placing chunkymap-signals.txt in the same folder as chunkymap-regen.py (see chunkymap-signals example.txt)

+	#where -t chunkymapregen just names the screen chunkymapregen
+	#Then if you are using screen and want to leave the output without terminating the process press Ctrl a d
+	#NOTE: now that loop is default, cron job scripts, which now disable loop for compatibility with new version, are ALL optional and NOT recommended
+    # ( to run only once, run: python chunkymap-regen.py --no-loop true )
+* Change program options (or stop it) while looping or rendering by placing chunkymap-signals.txt in the same directory as chunkymap-regen.py (see chunkymap-signals example files)
+	- to maintain stability of  your text editor, save the file, close it, then move/copy it to the directory (or save it as something else then rename it to chunkymap-signals.txt).
+* Has static html version of map (echo_chunkymap_table() php function) -- see example.php
 	* Zoom in and out
 	* optionally echo name of world that was detected by the scheduled py file
-	* shows player location (and only first 2 characters of name, for privacy; there is no saved setting yet, so to adjust, you must change the value of $nonprivate_name_beginning_char_count in chunkymap.php)

 	* Hide players if they stay in one spot long enough (see $player_file_age_expired_max_seconds in chunkymap.php) avoiding logout detection, and not requiring mods
-    
 * Has optional script to add crontab entry (to schedule update script every minute that runs the py file unless the py file is not complete [took longer than 1 minute])
