No Preprocessors in include

(explanation what this rule does, should go here. I don't know what the rule does)

This is a contributed rule, which means it is not part of the standard Prolint setup but you can download it separately from the Subversion reporistory and save it in your local prolint/contribs/rules path.
See http://www.oehive.org/node/1150 for more information on contributed rules.

Actually this is just an experiment, belonging to the proposal which is described in http://www.oehive.org/node/1150
