 Replying to [comment:4 ryandesign@…]:

 > Presumably the recommendation would not be printed if the recommended
 port is already installed.
 Yeah, that's pretty much what I had in mind.

 > I would like for each recommendation to be accompanied by an
 explanation. Users would want to know ''why'' a port is being recommended.
 For example, if they were told that yelp is used for accessing help
 content, and the user has no plans to access the help content, then the
 user will know they don't need to install it.
 Do you think that simply using the ${description} tag from each
 recommended port would be satisfactory?  It would require that authors use
 good descriptions.  Alternatively, I suppose a description {} keyword
 could be added to each recommends port line, like variant description {}
 already does.  Or it could be implemented such that if a description {} is
 not provided, then it defaults to the portfile's description tag.
