#### Center example usage:
```
./center-win.exe \
--port 7001 \
--systemid test \
--password test \
--sessions 10
```
Running this command will spawn an SMPP center (SMSC) which will:
- Start listening on 7001
- Accept clients with test:test credentials
- Allow up to a maximum of 10 sessions
#### Client example usage:
```
./client-win.exe \
--host localhost \
--port 7001 \
--systemid test \
--password test \
--window 5 \
--windowsleep 100 \
--messagecount 10000 \
--mps 10 \
--sessions 10
```
Running this command will spawn an SMPP client (ESME) which will:
- Try to connect 10 sessions to localhost:7001
- Once connected try to bind using test:test
- Once bound send 10000 messages at a rate of 10 per second and a window size of 5
- If the window is filled during sending the session will wait 100ms before attempting send again
