[ic] Catalog Building Tutorial - perl question

[kenshin]

This isn't an Interchange specific question but if any of you Perl guru's
out there can answer this for me I would be very grateful.

In the Catalog-Building Tutorial on page 34 there is some code that looks
like so:

for ($year .. $year + 7) {

What does the '..' do.  I could ot find it in any of my perl books (or maybe
i keep missing it).  Is it just short hand?

for ($year; $year <= $year + 7; $year++)

thanks
