+========
+Some more keys require the correct use of '==' and '=' depending
+on the kind of operation beeing an assignment or a match. Rules
+with invalid operations are skipped and logged to syslog. Please
+test with udevtest if the parsing of your rules throws errors and
+fix possibly broken rules.
