While attempting to clean up my Air's SSD, the estimable DaisyDisk showed me that 4 GB is being eaten up by Xcode DocSets. I like keeping my friends close and my SDK documentation closer, so I'd be happiest if I could maintain a copy of these DocSets on an external disk, so they're available offline but not cluttering my SSD.
The DocSets currently exist at
~/Library/Developer/Shared/Documentation/DocSets. Is it possible to move the
.docset files themselves to a different location (perhaps symlinking to them) without breaking Xcode's doc viewer?
