 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 ]]
+
+A preprocessor directive does not need to all be on one line. Also,
+multiple lines of *quoted* text can be used for a value. Examples:
+
+       \[[directive foo="baldersnatch"
+       bar="supercalifragalisticexpealadocious" baz=11]]
+
+       \[[directive text="
+       1. foo
+       2. bar
+       3. baz
+       more lines
+       "]]
