Thank you!

Could you write a commit message to introduce your changes? You can look
at those starting with "Add ..." in the code base.

Also, could you split it into two patches, one for each package?

The synopsis could be clarified, so could the description. In
particular, the latter explains what the library is about.

Ditto.

Could you send an updated patch?
