-Here's an example of how to run ikiwiki in a [[Subversion]] post-commit
-hook to automatically update a wiki as commits come in:
+If your wiki is kept in [[revision_control|rcs]], a post-commit hook is run
+every time you commit a change to your repository.

 
 

-       wiki_src=/path/to/checkout
-       wiki_dest=/path/to/web/server
-       svn up -q $wiki_src
-       ikiwiki $wiki_src $wiki_dest --wikiname=MyWiki
+ikiwiki generates the "post-commit hook" once you've uncommented the relevant
+section (under wrappers) in the ikiwiki.setup.

 
 

-This assumes that permissions allow anyone who commits to svn up the
-wiki_src directory and write to wiki_dest. If they don't, you'll need a
-suid wrapper to run the above as a user who can write to both.
+The generated wrapper is a C program that is designed to safely be made
+suid if necessary. It's hardcoded to run ikiwiki with the settings
+specified when you ran --wrapper, and can only be used to update and
+compile that one checkout into the specified html directory.
+
+Depending on your setup, the post-commit hook might end up
+getting called by users who have write access to the repository, but not to
+your wiki checkout and html directory. If so, you can safely make
+the wrapper suid to a user who can write there (*not* to root!). You might
+want to read [[Security]] first.
+
+[[Setup]] explains setting this up from the start and see [[rcs/details]] to
+know more.
