+The filename and directory are separate parameters because of
+some security checks done to avoid symlink attacks. Before writing a file,
+it checks to make sure there's not a symlink with its name, to avoid
+following the symlink. If the filename parameter includes a subdirectory
+to put the file in, it also checks if that subdirectory is a symlink, etc.
+The directory parameter, however, is not checked for symlinks. So,
+generally the directory parameter is a trusted toplevel directory like
+the srcdir or destdir, and any subdirectories of this are included in the
+filename parameter.

For example, your plugin might want to override `displaytime`, to change
the html markup used when displaying a date. Or it might want to override
`IkiWiki::formattime`, to change how a date is formatted. Or perhaps you

By venturing into this territory, your plugin is becoming tightly tied to
