+summary: Integration with BibLaTex
+description: |
+    This test verifies that a texlive and biber work together. It checks that
+    a LaTeX source with BibLaTeX package with a biber backend compiles and the
+    a bibliography a reference to the bibilography appears in the resulting PDF
+    document.
