+Codec.Text.IConv
+================
+
+This is a Haskell binding to the `iconv()` C library function.
+
+The only module exported is `Codec.Text.IConv`, which provides a single
+function:
+
+    -- | Convert fromCharset toCharset input output
+    convert :: EncodingName -> EncodingName -> Lazy.ByteString -> Lazy.ByteString
+
+where `fromCharset` and `toCharset` are the names of the input and output
+character set encodings, and input and output are the input and output text
+as lazy ByteStrings. For example:
+
+     import qualified Codec.Text.IConv as IConv
+     import qualified Data.ByteString.Lazy as BS
+     
+     main = do
+       -- read UTF8, but convert to UTF32 internally
+       content <- fmap (IConv.convert "UTF-8" "UTF-32") (BS.readFile file)
+       ...
+
+An [example program], similar to the iconv program, is included.
