Documentation will come later.

For the moment, edit the getPrices.pl file to have
the correct URL for your eqDKP site.  Run the script
(you CAN run perl scripts, right?) and then the mod
should display prices on many in-game tooltips.  If
something isn't working, find my as:
 - Lazare on Lightbringer US
 - Codayus on the #wowace IRC channel
 - cody@chaos.net.nz
 - Or just commit a fix to the SVN.  :-)

Most of the credit goes to Vita's DKP Tooltip mod and
to Ratings Buster.  The blame is mine alone.  :-)
