+## Preprocessor directives and wikilinks
+
+ikiwiki has two syntaxes for
+[[preprocessor_directives|PreprocessorDirective]].  The older syntax
+used spaces to distinguish between preprocessor directives and
+wikilinks; as a result, with that syntax in use, you cannot use spaces
+in WikiLinks, and must replace spaces with underscores.  The newer
+syntax, enabled with the `prefix_directives` option in an ikiwiki
+setup file, prefixes directives with `!`, and thus does not prevent
+links with spaces.  Future versions of ikiwiki will turn this option
+on by default.
