These have README.md files which when converted to (X)HTML using a
current version of pandoc show problems when validated using W3C Markup
Validator, see below.
Most of these problems are caused by using images without giving a name
(so the required alt attribute for <img> is not provided), or using <br>
instead of <br/>.
Pls fix these problems in your README.md files for your next release: in
all cases I inspected, the fixes were obvious and confirmation using
pandoc and W3C markup validator seemed unnecessary.
