@@ -4,31 +4,48 @@ Profile a single program giving stats for CPU, memory and other things (see man
 2 getrusage). The standard input is closed for the child process, so programs
 like `cat` or `xargs` can't be profiled (for now).
 
-## Example
+The following list is the data that this software can tell you (on Linux
+systems). The second list is all the features that are unmaintained for linux,
+maybe on other systems it could be useful.

+* user CPU time used
+* system CPU time used
+* maximum resident set size
+* page reclaims (soft page faults)
+* page faults (hard page faults)
+* block input operations
+* block output operations

+* involuntary context switches
