This package extends `org-re-reveal' with support for a
bibliography slide based on package `citeproc' with citation
support of Org mode 9.5.  Thus, Org `cite' links are translated
into hyperlinks to the bibliography slide upon export by
`org-re-reveal'.  Also, export to PDF via LaTeX and export to
HTML with Org's usual export functionality work.

This package is an alternative to `org-re-reveal-ref'.
While the latter which relies on `org-ref', `org-re-reveal-citeproc'
supports the new Org mode syntax introduced in in Org mode 9.5.
