+The application name is a word play on TeX and template, so the purpose seems
+quite obvious: we want to provide an easy and straightforward framework for
+reducing the typical code boilerplate when writing TeX documents.  Also note
+that one can easily extrapolate the use beyond articles and theses: the
+application is powerful enough to generate any text-based structure, given
+that a corresponding template exists.")
