+Version 4.50
+------------
+
+The exicyclog script has been updated to use three-digit numbers in rotated log 
+files if the maximum number to keep is greater than 99. If you are already 
+keeping more than 99, there will be an incompatible change when you upgrade. 
+You will probably want to rename your old log files to the new form before 
+running the new exicyclog. The following script, by Mick Swisher, can do this 
+for you:
+
+# Begin conversion
+# Rename all the old files by adding additional leading zeros.
+count=99
+while [ $count -gt 0 ]; do
+if [ $count -lt 100 ]; then newt=0$count; oldt=$count; fi
+if [ $count -lt 10 ]; then newt=00$count; oldt=0$count; fi
+if [ -f $mainlog.$oldt ]; then
+  $mv $mainlog.$oldt $mainlog.$newt
+elif [ -f $mainlog.$oldt.$suffix ]; then
