Thank you.

Could you fix some synopses and descriptions of added packages. In
particular, a synopsis cannot start with an article, and the description
is expected to consist of full sentences. At the very least, when
inspiration is not there, you can use "This package provides ..."
template.

Here you removed a decent synopsis+description with something less good.

I would remove the "used in" part, which is not useful.

Hmmm, no :)

See above.

Synopsis does not need to be titlecased.

Description should differ from synopsis.

> +    (synopsis "AST representation used by Serde derive macros")
> +    (description "AST representation used by Serde derive macros.  
> Unstable.")

Description should use full sentences.

> +    (synopsis "The bare essentials of std::io for use in no_std")

Don't start a synopsis with "The"

The first sentence is not complete.

I won't comment each description, you get the picture.

Could you send an updated patch?
