-[Modifiers](#language.modifiers) are little functions that are applied
-to a variable in the template before it is displayed or used in some
-other context. Modifiers can be chained together.

-The first parameter to the modifier plugin is the value on which the
-modifier is to operate. The rest of the parameters are optional,
-depending on what kind of operation is to be performed.
-
-The modifier has to [return](&url.php-manual;return) the result of its
-processing.
-
-This plugin basically aliases one of the built-in PHP functions. It does
-not have any additional parameters.
