 When I search (say, on Google) for a GHC-related bit of documentation, I
 variously get referred to old manuals. There doesn't seem to a good way
 for us, the GHC devs, to avoid this. But, perhaps we can include some
 information in the header of the pages to allow visitors to link to the
 latest manual, or perhaps to several versions. This header should also
 include the version number of the GHC that the page is documenting;
 currently, this info is only in the URL.
