Cycling Through All DBs With Startup Stored Proc

I have the following stored procedure set up as a startup procedure in the master database. I was lead to it from a microsoft SQL server news group and I have found that it is very helpful. I have been told, though, that it only runs on the master database at startup, but I need it to run for all of the databases on my server. (I'm a newbie and can't follow the code myself). How can this stored proc be modified so that it runs on all of the databases on my server at startup.

Any help is greatly appreciated. Thanks in advance!
