+process-qq: A Quasi-Quoter to execute processes
+===============================================
+
+# About
+
+This is a simple package for executing external process using quasi-quoters.
+
+# Install
+
+~~~ {.bash}
+$ cabal update
+$ cabal install process-qq
+~~~
+
+# API
+
+process-qq has three quasi-quoters, `cmd`, `lcmd` and `enumCmd`.
+
+The result type of `cmd` is `(Strict) ByteString`,
+`lcmd` is `Lazy ByteString`,
+`enumCmd`'s is `MonadIO m => Enumerator ByteString m a`.
+
+Command is failed, an Exception is thrown.
+
+Command is executed in ***run-time***, not compile-time.
+
+# Example
+
+* Invoke a process simply
+
+~~~ {.haskell}
+{-# LANGUAGE QuasiQuotes #-}
+import System.Process.QQ
+
+main = print =<< [cmd|ls|]
+~~~
+
+* Enumerate a process
+
+~~~ {.haskell}
+main =
+  run_ $ [enumCmd|curl http://www.google.com/|] $$ iterHandle stdout
+~~~
+
+* Unquoting (syntax is same as [shakespeare-text](http://hackage.haskell.org/package/shakespeare-text))
+
+~~~ {.haskell}
+main = do
+  [url] <- getArgs
+  print =<< [cmd|curl #{url}|]
