+    (description
+     "Light LaTeX Make (llmk) is yet another build tool specific for LaTeX
+documents.  Its aim is to provide a simple way to specify a workflow of
+processing LaTeX documents and encourage people to always explicitly show the
+right workflow for each document.  You can describe the workflows either in an
+external file @file{llmk.toml} or in a LaTeX document source in the form of
+magic comments.  It provides a uniform way to describe the workflows available
+for nearly all TeX environments, and behaves exactly the same in any
+environment.  At this point, @command{llmk} intentionally does not provide any
+method for user configuration.  Therefore one can guarantee that for a LaTeX
+document with an llmk setup, the process of typesetting the document will be
+reproduced in any TeX environment with the program.")
