It's matching against the item sku.  ^ matches against the beginning of 
a line, so it means start the match at the beginning of the sku, () is 
grouping, the ?: means to not save the match inside the grouping and | 
separates multiple possibilities.  So basically it's saying to match 
against a sku that either begins with FM or begins with WS followed 
immediately by one of 30, 35, 40 or 45.  For more information about perl 
regular expressions see <http://search.cpan.org/dist/perl/pod/perlre.pod>.
