LGP Startup/Shutdown Script

My first NSIS contribution... I'm so excited. 😁

I just released an ALPHA version of my Local Group Policy Startup/Shutdown Script header on the Wiki.

LGP Startup/Shutdown Script

I would greatly appreciate any feedback on it.

I updated the code to permit transparent use of the functions during un.installations. Took me a bit to figure it out but think the solution is quite elegant.

## Example:
    !define LGPScript::Create "!insertmacro _LGPScript_Create"
    !macro _LGPScript_Create Mode Command Parameters ReturnCode
        Push "${Mode}"
        Push "${Command}"
        Push "${Parameters}"
        !ifdef __UNINSTALL__
            Call un._LGPScript_Create
        !else
            Call _LGPScript_Create
        !endif
        Pop ${Returncode}
    !macroend
