<br>
I had a quick look at "opam weather services" reports and I am a bit puzzled at how the statistic are computed. It seems that a package is considered as "broken" when one of its dependency cannot be installed. I'm not sure it makes sense: in the case the dependency is not available on a given platform / compiler version, then all the packages which depend upon it are not available as well as "availability" is a transitive relation in opam. These packages are not "broken".<br>
<br>
Especially, on that page: <a href="http://ows.irill.org/table.html" target="_blank">http://ows.irill.org/table.html</a> a lot of "bad" result are in fact simply a result the package not available for the given compiler version.<br>
<br>
I'm sure they are packages which are actually broken (ie. there are no version of ocaml where they can be installed) and these should be much more useful to high-light in order than someone try to fix the descriptions (for instance me, when I am bored and have nothing else to do).<br>
<br>
Best,<br>
Thomas<br>
