 Just as `tlobsd tlmgr`, this command requires the `subversion` package.
 
+### `biber`
+
+A binay version of `biber`, the backend processor for BibLaTeX, is
+available for TeX Live for OpenBSD.  It can be installed or updated
+with `tlobsd` as follows:
+
+```sh
+tlobsd getbiber
+```
+
+This commands downloads a `biber` executable and attempts to verify it
+with the public key that is used to sign the TeX Live for OpenBSD
+binaries.  See
+[above](#installing-tex-live-on-openbsd-with-ready-to-use-binaries). 
+
+Direct link to `biber` binary: <https://www.ekdosis.org/texlive>.  This
+binary can be installed by hand into the TeX Live binary directory.
+The suffix must be removed and the file renamed to exactly "`biber`".
