+# "inputenc" is a base LaTeX package that provides an extensible framework
+# for conversion of a document encoding into an "LaTeX Internal Character
+# Representation" (LICR) and a set of encoding definitions
+# (<LaTeX name>.def files). Additional encoding definitions are provided by
+# several language support packages.
