Hmmm? I'm not sure if this is a practical solution because the old
emacs-leim package is just obsolete, if a new emacs package is
installed. How can i describe this inter-package dependency?
There's no way to express any version specific requirements. Once the
old emacs package gets demoted to [prev], it becomes a second class
citizen. In order to use it the user would have to know to set 'emacs'
to [prev] as well as 'emacs-leim' to [prev] as well (you can state this
in the release announcement.) Or in other words, upgrading to the v22
emacs package should have the effect of also uninstalling v21
emacs-leim, which is accomplished by installing the new [curr] of both
packages. Here I'm assuming that having a v22 emacs and a v21
emacs-leim both installed at the same time causes breakage.
