Forcibly remove a site

I got into a situation a while back where our primary site became corrupted and we didn't have a backup for some reason.

We tried uninstalling the site and re-installing and while it fixed the primary site problems it badly messed up the syncing with the central site.

In the end we followed the process below:

1. Revert the primary site to a central site
2. On the Central Site run:
   Preinst /delsite SiteCode ParentSite
   Preinst /deljob SiteCode
3. On the old Primary site run:
   Preinst /deljob SiteCode
4. Convert the old Primary site back to a primary site with the Central as it's parent
5. Run Preinst /keyforchild on the central site and copy to \inboxes\hman.box
6. Run Preinst /keyforparent on the primary site and copy to \inboxes\hman.box
7. Run Preinst /Syncchild:SiteCode on the Central Site
8. Run Preinst /syncparent on the primary site

This thankfully brought our sites back to life.
