You can use the `shell.nix` from this directory
to build the servant packages or even the tutorial
or cookbook if you want to, optionally.
Just the servant packages:
``` sh
$ nix-shell nix/shell.nix
```
Everything needed for the tutorial and the
cookbook too:
``` sh
$ nix-shell nix/shell.nix --arg tutorial true
```
The `shell.nix` file also supports specifying
a particular ghc version, e.g:
``` sh
$ nix-shell nix/shell.nix --argstr compiler ghcHEAD
```
