+The application 'convert' is used to convert an old format tracefile into a new
+format tracefile. It has several commandline parameters, the first is process file
+name, the second is a number (the number of cpu in the machine), the third is
+the first tracefile name(corresponding to the first cpu), the fourth is the
+second tracefile name(corresponding to the second cpu), the fifth is ...,
+the last one is root directory for the new trace (this can be omitted,
+by default it is 'foo')
+
+The command line looks like this:
+ ./convert processfile_name the_number_of_cpu first_tracefile_name, ..., foo_dir
+
+There is also a script file 'sysInfo' which is used to get system information
+from your local machine, the information is saved in 'sysInfo.out' which will
+be read by 'convert' later. If the old tracefile is generated by other machine,
+then the 'sysInfo.out' should be gotten from that machine.
+
+'core.xml' is a facility file, after run 'convert', it needs to be copied to
+'foo_dir/eventdefs' directory
