 # Changes in this version:
 #===============================================================
 # *"\?" in a variable will now be replaced with a simple ?
 #  before processing, remember to double escape that because
-#  json (=> \\?)
+#  json doesn't like \? (=> \\?)
 # *commands are now not run over and over again if not needed
-#
+# *files are now not rewritten for each variable individually
+# *some technical stuff
 
 ################################################################
 # Exit codes:
 #===============================================================
 # 0 => normal exit
-# 1 => argument error
+# 1 => command line argument error
 # 2 => error while processing
