<a name="line-18"></a><span class='hs-comment'>-- This module provides a type-based system for providing translations</span>

<a name="line-23"></a><span class='hs-comment'>-- The core idea is to create simple data type where each constructor</span>
<a name="line-24"></a><span class='hs-comment'>-- represents a phrase, sentence, paragraph, etc. For example:</span>
<a name="line-25"></a><span class='hs-comment'>--</span>
<a name="line-26"></a><span class='hs-comment'>-- > data AppMessages = Hello | Goodbye</span>
<a name="line-27"></a><span class='hs-comment'>--</span>
<a name="line-28"></a><span class='hs-comment'>-- The 'RenderMessage' class is used to retrieve the appropriate</span>
<a name="line-29"></a><span class='hs-comment'>-- translation for a message value:</span>

<a name="line-37"></a><span class='hs-comment'>-- Defining the translation type and providing the 'RenderMessage'</span>
