[DRE-maint] Bug#993251: ruby-kramdown: Package kramdown vanished without notice or transitional package

[Axel Beckert]

Package: ruby-kramdown
Version: 2.3.1-2

Hi,

aptitude refused to upgrade ruby-kramdown initially, because I have the
package "kramdown" installed and it has a hard dependency on
"ruby-kramdown (= 2.3.0-5)".

It seems that the package "kramdown" is no more built by the
ruby-kramdown source package. This opens a bunch of questions about this
questionable change:

* Why is it removed at all?
* Why is this not mentioned in the according debian/changelog entry?
* Why is there no transitional package?

So please either:

* Reinstantiate the kramdown package (my preferred choice), or
* if you really want to get rid of, at least provide a transitional
  package for the period of one Debian Stable release.

And:

* Mention (potentially retroactively) in the debian/changelog that and
  why it was removed or at least that it is now (i.e. with a future
  upload) a transitional package plus the reason for that.
