Preprocessor directives are similar to a [[WikiLink]] in form, except they
contain spaces and parameters. The general form is:
-\\[[directive param="value" param="value"]]
+ \[[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.
-Currently, these preprocessor directives are available:
+The quotes around values can be omitted if the value is a simple word.
+Also, some directives may use parameters without values, for example:
-* "inline" to make a [[blog]]
+ \[[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 ]]
