+bibliography is entirely controlled by LaTeX macros, facilitating the
+design of new bibliography and citation styles.  BibLaTeX uses its own
+data backend program \"biber\" to read and process the bibliographic
+data.  With biber, the range of features provided by biblatex
+includes:
+
+@enumerate
+@item
+full unicode support,
+
+@item
+customisable bibliography labels,
+
+@item
+multiple bibliographies in the same document, and
+
+@item
+subdivided bibliographies, such as bibliographies per chapter or
