     3  ## ping-pong
     4  
     5  `ping-pong.go` implements a simulation network which contains nodes running a
     6  simple "ping-pong" protocol where nodes send a ping message to all their
     7  connected peers every 10s and receive pong messages in return.
     8  
     9  To run the simulation, run `go run ping-pong.go` in one terminal to start the
    10  simulation API and `./ping-pong.sh` in another to start and connect the nodes:
    11  
    12  ```
    13  $ go run ping-pong.go
    14  INFO [08-15|13:53:49] using sim adapter
    15  INFO [08-15|13:53:49] starting simulation server on 0.0.0.0:8888...
    16  ```
    17  
    18  ```
    19  $ ./ping-pong.sh
    20  ---> 13:58:12 creating 10 nodes
    21  Created node01

    31  ```
    32  
    33  Use the `--adapter` flag to choose the adapter type:
    34  
    35  ```
    36  $ go run ping-pong.go --adapter exec
    37  INFO [08-15|14:01:14] using exec adapter                       tmpdir=/var/folders/k6/wpsgfg4n23ddbc6f5cnw5qg00000gn/T/p2p-example992833779
