    (synopsis "Command-line tool for accessing SPARQL endpoints over HTTP")
    (description "sparql-query is a command-line tool for accessing SPARQL
endpoints over HTTP.  It has been intentionally designed to 'feel' similar to
tools for interrogating SQL databases. For example, you can enter a query over
several lines, using a semi-colon at the end of a line to indicate the end of
your query.  It also supports readline so that you can more easily recall and
edit previous queries, even across sessions. It can be used non-interactively,
for example from a shell script.")
