It looks like something isn't completely right with those pages.
Afaict, each release-specific sub-page (ie: visp/Jade, etc) contains a PackageHeader(..)
macro invocation, which seems to cause the version rockers to be included on the page, but then the top page (wiki/visp) seems to use include(..)
statements that are guarded by wiki version(..)
macros. The combination of those two might be the reason things aren't quite working.
An alternative that's always worked for me is to create a top page with a single PackageHeader(..)
and then the release-specific sub-pages only contain the rest of the information (so no PackageHeader
s).
It's probably best to let the author/maintainer of visp
know about this. I suggest you report an issue on the visp
issue tracker.
