+    <para>
+      In this document and related Nix expressions we use the term
+      <emphasis>Beam</emphasis> to describe the environment. Beam is
+      the name of the Erlang Virtial Machine and, as far as we know,
+      from a packaging perspective all languages that run on Beam are
+      interchangable. The things that do change, like the build
+      system, are transperant to the users of the package. So we make
+      no distinction.

+      By default Rebar3 wants to manage it's own dependencies. In the

+      is not. To support this we have created two versions of rebar3,
+      <literal>rebar3</literal> and <literal>rebar3-open</literal>. The
+      <literal>rebar3</literal> version has been patched to remove the
+      ability to download anything from it. If you are not running it a
+      nix-shell or a nix-build then its probably not going to work for
+      you. <literal>rebar3-open</literal> is the normal, un-modified
+      rebar3. It should work exactly as would any other version of
+      rebar3. Any Erlang package should rely on
+      <literal>rebar3</literal> and thats really what you should be

-      To make life easier for our users, it makes good sense to go

-    <para>

+                                system](http://growl.info/). ## Setup ```Elixir
+                                defp deps do [ {:growl, github:
+                                \"zhallett/growl\"} ] ``` ## Usage Within the
+                                script you would like to create a `growl`
+                                notification, make the module call as follows:
+                                ```Elixir Growl.notify(\"This is a
+                                notification\") ``` The API accepts messages in
+                                a string format, as well as a list. If the first
+                                argument is a list, the first object is the
+                                title line, with subsequent lines being the body
+                                of the notification. ```Elixir
+                                Growl.notify([\"Example\", \"This is an example
+                                notification\"]) ``` would give the following
+                                notification: ![Forced
+                                Update](https://github.com/zhallett/growl/blob/master/multi_line_notification.png?raw=true

+                                using sidejob:call or sidejob:cast respectively.
+                                This library was originally written to support

+                                easier for human use and more compact. It

+                                also permutes the alphabet so that the easier
+                                characters are the ones that occur more
+                                frequently. It compactly encodes bitstrings

+                                omits trailing padding characters. z-base-32 was

+%%% @doc
+%%% The purpose of this command is to prepare a rebar3 project so that
+%%% rebar3 understands that the dependencies are all already
+%%% installed. If you want a hygienic build on nix then you must run
+%%% this command before running rebar3. I suggest that you add a
+%%% `Makefile` to your project and have the bootstrap command be a
+%%% dependency of the build commands. See the nix documentation for
+%%% more information.
+%%%
+%%% This command designed to have as few dependencies as possible so
+%%% that it can be a dependency of root level packages like rebar3. To
+%%% that end it does many things in a fairly simplistic way. That is
+%%% by design.
+%%%
+%%% ### Assumptions
+%%%
+%%% This command makes the following assumptions:
+%%%
+%%% * It is run in a nix-shell or nix-build environment
+%%% * that all dependencies have been added to the ERL_LIBS
+%%%   Environment Variable

-				used to limit the number of concurrent get/put

-				with {error, overload} if the limit is ever hit.

+%%% The purpose of this command is to prepare a rebar3 project so that
+%%% rebar3 understands that the dependencies are all already
+%%% installed. If you want a hygienic build on nix then you must run
+%%% this command before running rebar3. I suggest that you add a
+%%% `Makefile` to your project and have the bootstrap command be a
+%%% dependency of the build commands. See the nix documentation for
+%%% more information.
+%%%
+%%% This command designed to have as few dependencies as possible so
+%%% that it can be a dependency of root level packages like rebar3. To
+%%% that end it does many things in a fairly simplistic way. That is
+%%% by design.
+%%%
+%%% ### Assumptions
+%%%
+%%% This command makes the following assumptions:
+%%%
+%%% * It is run in a nix-shell or nix-build environment
+%%% * that all dependencies have been added to the ERL_LIBS
+%%%   Environment Variable
