+# Author: Günter Milde <milde@users.berlios.de>
+# 
+# 2008-12-04 first published version
+# 2009-02-02 use name Labeling for "LyX-List/Labeling" list type,
+# 	     copy standard layout verbatim for failsave working with 
+#	     both KOMA and non-KOMA document classes
+# 2010-11-16 use Require keyword instead of \usepackage in preamble
+#
+# The package enumitem provides user control over the layout of the three
+# basic list environments: enumerate, itemize and description. It supersedes
+# both enumerate and mdwlist (providing well-structured replacements for all
+# their funtionality), and in addition provides functions to compute the
+# layout of labels, and to ‘clone’ the standard environments, to create new
+# environments with counters of their own.
+#
+# - fancy labels and fancy refs,
+# - leftmargin, labelsep and labelwidth automatically set,
+# - changes applied globally or only in one of the three
+#   types or even in a single list (including topsep),
+# - several description styles (which fix some bad spacing, too),
+# - starting value and counter resuming,
+# - trivlists properly formatted,
+# - control on page breaking
+#
+# Styling the basic lists is possible 
+#
+# a) generally in the LaTeX preamble and 
+# b) per environment with optional arguments
+#
+# See enumitem.pdf for details and examples.
+#    http://dante.ctan.org/CTAN/macros/latex/contrib/enumitem/enumitem.pdf
+#
+# TODO: since version 2.0, enumitem supports "cloning" of lists.
+#       Producing a labeling as clone of a description allows
+#       Preamble-Styling specific to this list type.
