+diff
+====
+
+A difference algorithm package for go.
+
+The algorithm is described by Eugene Myers in
+["An O(ND) Difference Algorithm and its Variations"](http://www.xmailserver.org/diff2.pdf).
+
+Example
+-------
+You can use diff.Ints, diff.Runes, diff.ByteStrings, and diff.Bytes
+
+    diff.Runes([]rune("sögen"), []rune("mögen")) // returns []Changes{{0,0,1,1}}
+
+or you can implement diff.Data
+
+    type MixedInput struct {
+    	A []int
+    	B []string
+    }
+    func (m *MixedInput) Equal(i, j int) bool {
+    	return m.A[i] == len(m.B[j])
+    }
+
+and call
+
+    m := &MixedInput{..}
+    diff.Diff(len(m.A), len(m.B), m)
+
+Also has granularity functions to merge changes that are close by.
+
+    diff.Granular(1, diff.ByteStrings("emtire", "umpire")) // returns []Changes{{0,0,3,3}}
