+# servant-nix
+
+Use Nix expressions as request or response bodies in servant applications
+
+![servant](https://raw.githubusercontent.com/haskell-servant/servant/master/servant.png)
+
+## Example
+
+Run the example:
+
+```
+cabal new-test
+```
+
+It performs a simple roundtrip test for a fixed Nix expression
+which is a list of numbers. See the code in `example/Main.hs`.
