    12 			The <a href="https://www.mercurial-scm.org/">Mercurial</a> version control system 

    13 			can provide the repository commit log in a machine readable format – XML.

    14 			We will transform this XML to relations using the <code>relpipe-in-xmltable</code>

    15 			and then filter records using the SQL language in the <code>relpipe-tr-sql</code> tool.

    16 			Everything on-the-fly, in a single shell pipeline. Of course, we can cache intermediate products in a file if needed.

    25 		<p>

    26 			Using different output filter than <code>relpipe-out-tabular</code>,

    27 			we can serialize the relational output into other formats (XML, CSV, Recfile, ODS, ASN.1 BER etc.),

    28 			display them in a GUI or execute some shell command for each record.
