+I'm writing a plugin to wikify c/c++ code.
+
+By default ikiwiki generates xxx.html for a file called xxx.c.
+
+The problem is that I occasionally have xxx.c and xxx.h in the same directory and there's a filename collision.
+
+My solution is to allow plugins to provide a hook that sets the pagename. --[[/users/bstpierre]]
