Usefulness for xymonconfigsync?

I've seen this link:

http://sourceforge.net/projects/xymonconfigsync/

Could some of you please share what are some of the ways in which you are using this?

Thank you, and I am sorry if this has been answered before, I've not found it. I am trying to establish an active/standby setup and am running into issues which I hope this might help with.
