+     "This package provides for LuaLaTeX an ArabTeX-like interface to generate
+Arabic writing from an ascii transliteration.  It is particularly well-suited
+for complex documents such as technical documents or critical editions where
+a lot of left-to-right commands intertwine with Arabic writing.
+@code{arabluatex} is able to process any ArabTeX input notation.  Its output
+can be set in the same modes of vocalization as ArabTeX, or in different roman
+transliterations.  It further allows many typographical refinements.  It will
+eventually interact with some other packages yet to come to produce from
+@file{.tex} source files, in addition to printed books, TEI XML compliant
+critical editions and/or lexicons that can be searched, analyzed and
+correlated in various ways.")
