Reading directory contents

["Ashley M. Kirchner" <ashley@xxxxxxxxxx>]

   A file system question for you folks.

   We have a folder that contains the following structure of files for 
each of our sales reps in the company:

   $TOP_FOLDER$/
               /$SalesRep1/
                          /$Client1/
                                   /File1.ext
                          /$Client2/
                                   /File1.ext
                                   /File2.ext
               /$SalesRep2/
                          /$Client1/
                                   /File1.ext
                          /$Client2/
                                   /File1.ext
                                   /File2.ext
                          /$Client3/
                                   /File1.ext
                                   /File2.ext
                                   /File3.ext
   etc., etc.

   What I'd like to do it iterate through this $TOP_FOLDER$ and 
generate a page that looks as follows:

   $SalesRep1   Clients: 2      Files: 3      Total size: xxx [MB/GB]
   $SalesRep2   Clients: 3      Files: 6      Total size: xxx [MB/GB]
   etc., etc.

   So I need to traverse through all the directories, while counting 
stuff at the same time (ignoring . and .. as I go) and at the end do 
some pretty display of all the information (I can figure that out later, 
I just need to collect data right now.)

   Right now, when I do an opendir() and readdir() I only get the 
contents of the top folder.  How do I get the rest, and count the data 
as well?
