+#DescriptionBegin
+# Adds a 'Minipage (Var. Width)' inset using the varwidth LaTeX package.
+# The varwidth package provides a variable-width minipage, whose resulting
+# width is the width of its contents (if this does not exceed the specified
+# maximum width).
+#
+# The inset has two optional arguments: vertical adjustment (c|t|b) and
+# maximum width (defaults to \linewidth).
