 // Diskfs exports the file system on the disk.
+//
+// Usage:
+// 	diskfs [-D] [-P profport] [-a addr] [-p port] root
+// Diskfs exports file system on the disk rooted at root.
 // By default it listens to 127.0.0.1:5640.
 // You can change the address and port number with -a and -p flags.
+// The -D flag enables very chatty log messages.
+// The -P flag enables the pprof web interface at the the port profport.
+// The address the pprof listens to is the same as addr (or 127.0.0.1 if
+// -a flag is not specified).
