+Preprocessor directives are similar to a [[WikiLink]] in form, except they
+contain spaces and parameters. The general form is:
+
+       \[[directive param="value" param="value"]]
+
+This gets expanded before the rest of the page is processed, and can be used
+to transform the page in various ways.
+
+The quotes around values can be omitted if the value is a simple word.
+Also, some directives may use parameters without values, for example:
+
+       \[[tag foo]]
+
+Note that if a preprocessor directive has no parameters, a space still must
+be put after its name, to avoid confusion with a [[WikiLink]]. For example:
+
+       \[[pagecount ]]
+
+A preprocessor directive does not need to all be on one line, it can be
+wrapped to multiple lines if you like:
+       
+       \[[directive foo="baldersnatch"
+       bar="supercalifragalisticexpealadocious" baz=11]]
+
+Also, multiple lines of *quoted* text can be used for a value.
+To allow quote marks inside the quoted text, delimit the block
+of text with triple-quotes:
+
+       \[[directive text="""
+       1. "foo"
+       2. "bar"
+       3. "baz"
+       """]]
