It would be very useful to make use of variables while building Wikis.

Sometimes you wish to refer to a folder, or a version number, or a dynamic info that might change from time to time, and you need to change all occurrences along the wikis.

Maybe the variables placeholders could be replaced by either database preconfigured key-pair values, as also by Ruby functions that calculate the value for that variable in runtime at request time.
