-// This code exists to shuffle file descriptors, which is commonly needed when
-// forking subprocesses. The naive approach (just call dup2 to set up the
-// desired descriptors) is very simple, but wrong: it won't handle edge cases
-// (like mapping 0 -> 1, 1 -> 0) correctly.
-//
-// In order to unittest this code, it's broken into the abstract action (an
-// injective multimap) and the concrete code for dealing with file descriptors.
-// Users should use the code like this:
-//   base::InjectiveMultimap file_descriptor_map;
-//   file_descriptor_map.push_back(base::InjectionArc(devnull, 0, true));
-//   file_descriptor_map.push_back(base::InjectionArc(devnull, 2, true));
-//   file_descriptor_map.push_back(base::InjectionArc(pipe[1], 1, true));
-//   base::ShuffleFileDescriptors(file_descriptor_map);
-//
-// and trust the the Right Thing will get done.
