# 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.
#
# 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.
