Integrating git version control into a plugin to track changes in save games

[raath]

I'm a PHP developer and I use git a lot as part of my every day routine.

For me, git is the perfect means of keeping a historical record of changes and looking at the structure of the save files, git is the perfect method of backing up save games. At the moment I'm having a bad time with my mun base and other landed craft. For no reason, my structures keep ending up under the surface so I have to track down a previous save game and hope that I can return them to their original altitude. With Git, I could go through the commits to the point of time when the structures end up under the surface and restore them and save me a few hours of rapid disassembly while I try and find it's original altitude.

My idea is to write a simple plugin that will fire a git commit command when a game is saved so I don't have to remember to do it manually. Then if things start teleporting into the planet or other odd nastiness happens to ruin the game, I can hunt through the version history and restore the original altitudes thus rescuing my game.

As I said I'm a LAMP developer, working on linux, some python experience so the transition to C# hopefully won't be that painless. I'm looking for some hints and tips to get me fast tracked.

First problem I have in my quest is that I've discovered there is an OnSave method but MonoDevelop doesn't seem to like my code.

using System;
using UnityEngine;

namespace VersionKontrol
{
  class KerbalVersionKontrol : PartModule
  {
    public override void onSave (ConfigNode node)
    {
      print ("** Here be some git magic eventually **");
    }
  }
}

I'll be executing git commit -a -m "<saveType> <ISO date string>"

but when I build MonoDevelop tells me

'VersionKontrol.KerbalVersionKontrol.onSave(ConfigNode)' is marked as an override but no suitable method found to override

Is there also a method to call when a save game is created? so I could fire git init in that save game directory?

C# is case sensitive, so onSave won't work - it needs to be OnSave
