 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |

else
result = frame.args[1] or ''; -- no value (nil or empty string) so this is a preview
end
return result
end
--[[
pmain
This function returns the either the first argument or second argument passed to this module's parent (i.e. template using this module), depending on whether it is being previewed.
Usage:
{{#invoke:If preview|pmain}}

This function returns the either true or false, depending on whether it is being previewed.
Usage:
{{#invoke:If preview|boolean}}
