+# Profile
+
+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
+
+ > ./profile echo hello world
+ user CPU time used: 0 3333
+ system CPU time used: 0 0
+ residet set size used: 2336
+
+## TODO
+
+* [x] user CPU time used
+* [x] system CPU time used
+* [x] maximum resident set size
+* [ ] integral shared memory size
+* [ ] integral unshared data size
+* [ ] integral unshared stack size
+* [ ] page reclaims (soft page faults)
+* [ ] page faults (hard page faults)
+* [ ] swaps
+* [ ] block input operations
+* [ ] block output operations
+* [ ] IPC messages sent
+* [ ] IPC messages received
+* [ ] signals received
+* [ ] voluntary context switches
+* [ ] involuntary context switches
