+# ================================
+
+# "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.
+#
+# The following encodings from http://www.ctan.org/pkg/latex-cyrillic are
+# not included, because they are not widely used and lack iconv support:
+# ctt, dbk, isoir111, koi8-ru, lcyenc, maccyr, macukr, mik, mls, mnk, mos,
