-## 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.
