// This is a dotnet-script file to help with redeploying the PiSlicedDayPhotos program to a Raspberry Pi - if you
// are only running a single pi/instance of the program this is probably not that useful. But if you are running 
// a number of cameras this might be useful to re-deploy to all of them.
//
// There are many possible ways to script/run this - I currently run it via Pointless Waymarks PowerShell runner -
// https://github.com/cmiles/PointlessWaymarksProject/tree/main/PointlessWaymarks.PowershellRunnerGui -
// to save it with my other scripts and to make it easier to store the various hosts/usernames/passwords
// with 'good enough' security.
//
// To run this script you will need dotnet-script installed - see https://github.com/dotnet-script/dotnet-script -
// take care that it is appropriate and works with your setup but 'dotnet tool install -g dotnet-script' is usually a good
// place to start. You can then run this:
//   dotnet-script [Path]\RedeployPiSlicedDayPhotos.csx -- [PiUserName] [PiPassword] [PiHostName]
