How to obtain the latest version of SPARQL 1.1 test cases?

Hi,

What is the best way to obtain the latest version of the SPARQL 1.1 test
cases?  The main website [1] includes a link to an archive file [2] that
upon first glance seems to contain everything.  Looking a little bit deeper
into this, it turns out that the content of the website [1] and the content
in the archive file [2] are not completely the same.  For example, [3]
includes RIF test cases that are not in the archive.

[1] https://www.w3.org/2009/sparql/docs/tests/
[2]
https://www.w3.org/2009/sparql/docs/tests/sparql11-test-suite-20121023.tar.gz
[3] https://www.w3.org/2009/sparql/docs/tests/data-sparql11/entailment/

In case the site [1] contains the newest version and the archive [2] is
outdated, what would be the best way to scrape the newest content from the
web site?  I have tried to do this with the following command, but standard
download tools are unable to follow links from Turtle-formatted manifest
files, so I do not get all the content that is on the site and that is
linked to from some manifest file:

```
$ wget --recursive --page-requisites --convert-links --no-parent
https://www.w3.org/2009/sparql/docs/tests/
```

Thanks for making this collection of test cases available.  This helps
developers a lot.
