Please expound a little bit.  Otherwise OK.

Thanks for reviewing all of these!

The problem with this and some other libraries is that the library
doesn't have an official home-page (apart from a source repository
which doesn't include anything other than the source). The description
is taken one-to-one from the Cabal file and I don't really know how I
can expand the description.

The Cabal file of some other libraries like, e.g., ghc-network, give
an, IMO, too detailed description (sometimes even with a code
snippet):

...
description:
  This package provides a low-level networking interface.
  .
  In network-2.6 the @Network.URI@ module was split off into its own
  package, network-uri-2.6. If you're using the @Network.URI@ module
  you can automatically get it from the right package by adding this
  to your .cabal file:
  .
  > flag network-uri
  >   description: Get Network.URI from the network-uri package
  >   default: True
  >
  > library
  >   -- ...
  >   if flag(network-uri)
  >     build-depends: network-uri >= 2.6, network >= 2.6
  >   else
  >     build-depends: network-uri < 2.6, network < 2.6
  .
  That is, get the module from either network < 2.6 or from
  network-uri >= 2.6.
...

... and they also only have a source repository with no high level
information. For this reason I did cut the description to the,
sometimes very short, high level piece.

I hope it's fine to keep the concise description for these.

Fede

Often there’s a README or manual that gives a better overview, but yeah,
I don’t mean that you should spend another 10 hours on this.  ;-)  So if
you find a paragraph that’s clearer, that’s nice, otherwise it’s OK.

Agreed, something like this one is overly detailed.
