The hook can be called if one package is upgraded with another,
before a package is removed and before a package is installed, etc.

I guess the hooks will be distributed in a package
   CSWpkghooks
or something. It should be updated before any other package on each
update invocation and allows fixing these ugly things by calling
scripts before malicous actions can take place. As I wrote before
this would have allowed for the complicated XML-transition from
Ben, the esound-problem, package renames and all other weird
stuff. It is *the* chance to clean up once and for all.


Best regards
