+%description
+When editing HTML it's easy to make mistakes. Wouldn't it be nice if
+there was a simple way to fix these mistakes automatically and tidy up
+sloppy editing into nicely laid out markup? Well now there is! Dave
+Raggett's HTML TIDY is a free utility for doing just that. It also
+works great on the atrociously hard to read markup generated by
+specialized HTML editors and conversion tools, and can help you
+identify where you need to pay further attention on making your pages
+more accessible to people with disabilities.
