Comment(by eturro@…):

 May I suggest an entry is added to the MacPorts wiki specifying which
 Xcode files are actually needed by MacPorts? As the "disk space is cheap"
 mantra is valid for HDDs but not for SSDs, and since Xcode now comes with
 a lot of iOS stuff which many users might not need, an entry explaining
 how they can "trim down" their Xcode install without deleterious
 consequences would be very welcome, wouldn't you agree?
