+Ptrace Rules
+------------
+
+There are four classes of ptrace operations:
+
+- `trace`: trace another process using `ptrace`
+- `tracedby`: be traced using `ptrace` by another process
+- `read`: read certain proc filesystem information, kcmp, futexes, and perf trace events about another process
+- `readby`: have certain proc filesystem information, kcmp, futexes, and perf trace events about oneself read by another process
+
+The `peer=` option can be included to limit the profiles that the other process must be running under.
+
+Example:
+
+
+```
+ /profile {
+   ptrace, # Allow all ptrace operations
+   ptrace (readby, tracedby) peer=unconfined, # Allow unconfined processes to ptrace us
+ }
+```
