Copy this script to `genieacs/config/ext/ext-runner.js`

Then from your genieacs dir run `node config/ext/ext-runner.js`. It will then list out your scripts and the exported functions, simliar to

> $ node config/ext/ext-runner.js  
> Must provide name of script and command to run.  
> Usage: node config/ext/ext-runner.js SCRIPT\_NAME FUNCTION  
> Script: Function:  
> cpe-config portForwards, staticReservations, resetPppoe, getConfig  
> events send, diagnostic  
> network ip

And to execute a script you would do: `node config/ext/ext-runner.js cpe-config getConfig`. That will run the getConfig func in the cpe-config script using the block of parameters in `let args = ...`
