 Synopsis:	regular expression like Perl/Ruby in Haskell
 Description:
-  Regular expression library like Perl/Ruby's regular expressions.
+  Regular expression library like Perl and Ruby's regular expressions.
   This package has a module RegexPR.
   And RegexPR export functions matchRegexPR and gsubRegexPR.
   .
-      matchRegexPR :: String -> Maybe ((String, (String, String)), [(Int, String)])
-  .
-      gmatchRegexPR :: String -> [((String, (String, String)), [(Int, String)])]
-  .
-      subRegexPR :: String -> String -> String
-  .
-      gsubRegexPR :: String -> String -> String
-  .
-      splitRegexPR :: String -> String -> [String]
-  .
-  Examples:
-  .
-  matchRegexPR "ab(cde)f\\1" "kkkabcdefcdefgh" =>
-               Just (("abcdefcde", ("kkk", "fgh")),[(1,"cde")])
-  .
-  matchRegexPR "(?<=hij)abc" "kkkabchijabcde" =>
-               Just (("abc",("kkkabchij","de")),[])
-  .
-  gsubRegexPR "\\G(\\d\\d\\d)" "\\1," "123456 789" => "123,456, 789"
-  .
-  subRegexPR "(?<=(.)(.)(.))e" " \\3\\2\\1 " "abcdefg" => "abcd dcb fg"
-  .
-  gsubRegexPR "(?ixm)  aBc  . # comment \n\n" "abc!" "abc\nABCDAbcAbc" =>
