Default /proc details?

Hi. I have just bought this book which looks useful; however, I am trying to find specific information on how to use the /proc filesystem to find cpu usage per process which is not covered. Any hint of where to look would be gratefully received!
I have worked exclusively in the Solaris environment up till this point so although I am not a unix newbie linux differs in certain ways including, sadly for me, a very different layout to /proc!

Thanks in advance...

There are a few descriptions of /proc round the web, a fairly good one is at

You are perhaps specifically looking for procinfo, which is usually in /usr/bin.

If you want to look at the source, then download a source source rpm and install it. By way of example one can be found in http://fr.rpmfind.net/linux/freshmeat/procinfo/.
Install it with rpm -iv, when it will appear in /usr/src/REDHAT/SOURCES, decompress with bzip2 -d, then extract the files with tar xvf.
