Ask HN: SVN updates summary

HN : I want to achieve the following.

I have checked out source code from a SVN server, which is not in my control. I would like to know whenever there are new updates available and classify those as modification, new additions etc. Googling led me to believe "svn status --show-updates" was the command I wa slooking for. However when I run it on the repository root, it does not gives me the A/M flags but just * in status column. Any ideas on how to get this? TIA.
