-# Welcome to the Frama-C Wiki.
-
-Is on-topic in this wiki anything that may be of help to others users of
-Frama-C and related tools: tips, changes that you have noticed,
-workarounds, etc. If it should have been in the manual, put it here. If
-it's too minute, platform-specific, or temporary to be a good fit for
-the manual, put it here. Your goal should be to make a wiki so clear and
-functional that it puts the authors of Frama-C's various manuals to
-shame.
-
-Do not be afraid to reorganize the words of others if you feel that
-makes the wiki more useful as a whole. They agreed to let you do that
-when they chose to participate, and so do you.
