> Let me try to provide a few hints; a package is reported as "bad" for a

> dependencies.
>
> This means that there is no way you can install it using opam, and even if
> the "code" shipped with the package may be perfectly fine, the "package"
> itself is nevertheless useless.
>
> This is why it is often termed "broken", following a terminology that is
> now standard in the world of package based distribution, as it has been in
> use for a couple of decades.
>
> Why a package is broken, who is responsible of fixing it, is another
> story: it can be the package maintainer that did not update the
> dependencies, or the maintainer of a dependency that has wrongly removed
> it, or the release manager that has not spotted the problem.

> In the framework of the Mancoosi project we have developed a full suite of

> happen that all these tools are even written in OCaml.

>> Hi,
>>
>> 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".
>>
>> Especially, on that page: http://ows.irill.org/table.html a lot of "bad"
>> result are in fact simply a result the package not available for the given
>> compiler version.
>>
>> 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).
>>
>> Best,
>> Thomas
