+# definition in /usr/share/texlive/texmf-dist/tex/latex/biblatex/biblatex.sty
+# and a corresponding $BCF_VERSION in lib/Biber/Constants.pm. Unfortunally,
+# Biber supports only one version of BCF. See "Compatibility Matrix" in
+# doc/biber.tex.
+# Because Biber does not use texlive-biblatex, Biber cannot Require it's exact
+# version. Because it is expensive to rebuild texlive, it's not good to
+# Require a specific biber version from texlive-biblatex.
+# Hence I proposed a bcfversion dependency which both packages can agree on
+# (bug #2048536).
