-# bibexport
-
-Export all cited references into a single bibtex file. This is
-most useful when writing collaboratively while using a large,
-private bibtex collection. Using the bibexport filter allows to
-create a reduced bibtex file suitable for sharing with
-collaborators.
-
-## Prerequisites
-
-This filter expects the `bibexport` executable to be installed
-and in the user's PATH.
-
-## Usage
-
-The filter runs `bibexport` on a temporary *aux* file, creating
-the file *bibexport.bib* on success. The name of the temporary
-*.aux* file can be set via the `auxfile` meta value; if no value
-is specified, *bibexport.aux* will be used as filename.
-
-Please note that `bibexport` prints messages to stdout. Pandoc
-should be called with the `-o` or `--output` option instead of
-redirecting stdout to a file. E.g.
-
-    pandoc --lua-filter=bibexport.lua article.md -o article.html
-
-or, when the filter is called in a one-off fashion
-
-    pandoc --lua-filter=bibexport.lua article.md -o /dev/null
-
