- Installing the `delimcc` library gives you Oleg's Delimited Continuation library for OCaml, which we will encourage you to play around with later in the term. It's not essential to have it, though. There are some advantages to using one of the 4.02.x versions of OCaml, though, rather than the 4.01.0 version I think most of us ended up installing. One advantage is that now you can use the special <code>#show <i>symbol</i></code> command in OCaml sessions, which works like Haskell's special <code>:info <i>symbol</i></code> inside a GHCi session. Then for example, instead of having to type:

-4. Next create a folder in your `$HOME` directory named `.juli8`. Download the Juli8 code from [[here|/code/Juli8-v1.3.tgz]]. That link will no doubt be updated frequently in April and May 2015. The current version is: 1.3, posted 5 April 2015. Copy the contents of the `Juli8` folder that you downloaded into the `$HOME/.juli8` folder that you created. (So `$HOME/.juli8` should contain folders `haskell`, `ocaml`, and so on.)

Now whenever you start up OCaml, the Juli8 OCaml libraries (including their monad components, which we'll be making extensive use of) will automatically be loaded. <!-- If later you want to load Oleg's Delimcc library, type `#load "delimcc.cma";;` then use the `Delimcc` module. -->
