 requires a 1.5 JDK to build and simply typing make should build it.
 
 It produces a jar file, logc.jar, that can be run on the
-hotspot.log from LogCompilation output like this:
+HotSpot log (by default, hotspot_pid{pid}.log) from LogCompilation output like this:
 
-  java -jar logc.jar hotspot.log
+  java -jar logc.jar hotspot_pid1234.log
 
 This will produce something like the normal PrintCompilation output.
 Adding the -i option with also report inlining like PrintInlining.
