# This recipe adds "(:pageaction ... :)" markup to control or change the
# default page action when a wiki page is accessed.  Examples:
#
#   (:pageaction print:)           # the wiki page will always be viewed with the print skin
#   (:pageaction print=browse:)    # disable the print skin
#
# To use this recipe, simply copy it into the cookbook/ directory, and
# add the following line to a local customization:
#
#   include_once("$FarmD/cookbook/page-action.php");

$RecipeInfo['PageAction']['Version'] = '2010-09-02';

# Catch all text between (:pageaction and :) and call PageAction with that text
