Solaris equivalent of dpkg -S

In the past I have spent quite some time trying to figure out what package did install a certain file on Solaris. What I wanted was really just the equivalent of dpkg -S /path/to/file. But those searches where not very fruitfull, even talking to more experienced Solaris admins didn't help, they could only tell me how to find out what files where in a certain package.

Today however, mostly by accident (I was trying to remember how to list the files in a package), I finally found it!
