+This tool greps through files for SIGNAL() or SLOT() macros and pipes the signals/slots
+through QMetaObject::normalizedSignature().
+
+Rationale: In connect statements, you'll get a micro-speed update when passing in normalized
+signatures for signals and slots.
+
+Run it without any arguments to see the command line parameters.
+
+Typical usage on Qt:
+
+# find all files with non-normalized signal/slot connections and p4 edit them
+normalize $QTDIR/src | xargs p4 edit
+# replace all non-normalized signal/slots
+normalize --modify $QTDIR/src
+# p4 diff to see that everything is OK then submit :)
+p4 submit $QTDIR/src/...
