+---------------

+* General usage

+
+        The text after //  in close pair is modifiers
+

+        m - close key jumps through multi line
+        s - close key jumps only in the same line
+        k[KEY] - map the close key to [KEY]
+
+            by default if open key equals close key the multi line is turn off
+
+            "<?": "?>"      ? jumps only in the same line
+            "<?": "?>//m"   force ? jumping through multi line
+            "<?php":"?>"    ? will jump through multi line
+            "<?php":"?>//s" force ? only jumping in the same line
+            "<?": "?>//n"   do not jump totally
+            "<?": "?>//k]"  use key ] to jump through ?>
+
+        for 'begin' 'end' pair, e is a charactor, if map e to jump will be annoy, so use modifier 'n' to skip key map
+
+        au FileType ruby     let b:AutoPairs = AutoPairsDefine({'begin': 'end//n]'})
+
+
+        input: begin

+        input: begin|end (press e on |)

+
+* Advanced usage
+
+        au FileType rust     let b:AutoPairs = AutoPairsDefine({'\w\zs<': '>'})
+
+        if press < after a word will generate the pair
+
+        when use regexp MUST use \zs to prevent catching
+        if use '\w<' without \zs,  for text hello<|> press <BS> on | will output 'hell', the 'o' has been deleted
+
+        pair: '\w\zs<': '>'
