Andrew,

My first thought is to create an associative array (directory object ?), and 
put the values of the "from"s into it as keys, with an associated value of 
1.  When the key already exists just increment the associated value.

After having done that you can iterate that associative array for any value 
thats not 1.

Rudy Wieser
