-- A StringTemplate is a String with \"holes\" in it.
-- This is a port of the Java StringTemplate library written by Terrence Parr.
-- (<http://www.stringtemplate.org>).
-- This library implements the basic 3.1 grammar, lacking group files
-- (though not groups themselves), Regions, and Interfaces.
-- The goal is not to blindly copy the StringTemplate API, but rather to
-- take its central ideas and implement them in a Haskellish manner.
-- Indentation and wrapping, for example, are implemented through the
-- HughesPJ Pretty Printing library. Calling toPPDoc on a StringTemplate
-- yields a Doc with appropriate paragraph-fill wrapping that can be
-- rendered in the usual fashion.
-- This library extends the current StringTemplate grammar by allowing the
-- application of alternating attributes to anonymous
-- as well as regular templates, including therefore sets of alternating
-- attributes.
-- Basic instances are provided of the StringTemplateShows and ToSElem class.
-- Any type deriving ToSElem can be passed automatically as a StringTemplate
-- attribute. This package can be installed with syb-with-class bindings
-- that provide a ToSElem instance for anything deriving
-- 'Data.Generics.SYB.WithClass.Basics.Data'. When defining an instance of
-- ToSElem that can take a format parameter, you should first define an
-- instance of StringTemplateShows, and then define an instance of ToSElem
-- where @ toSElem = stShowsToSE@.
