PmWiki could use that information to build a table of links.  The
table would allow an administrator to

1) See what version of each recipe is installed, and
2) Hit a link to see the page for each recipe.

For me, that would probably be enough.

Check out the "Infolister" Firefox plugin to see something similar.
