Comment(by ryandesign@…):

 Replying to [comment:4 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?

 What I meant to say was that because we have for years now subscribed to
 the idea that disk space is cheap (notwithstanding the fact that this does
 not apply to SSDs), consequences of this can be seen throughout MacPorts.
 The large Xcode install is not going to be the only place where you might
 experience greater disk usage than you, with an expensive disk, are
 comfortable with. I'm explaining that this is not easy to change in
 MacPorts at this time.

 I agree a document in the wiki about how to reclaim some disk space would
 be welcomed. Possible subtopics could include removing parts of Xcode that
 aren't needed, removing distfiles, uninstalling inactive ports,
 uninstalling leaves, cleaning failed partial builds, .... I don't have
 time to write this document now, but anyone else should feel free to do
 so; the wiki is open for anyone with a Trac account to edit.
