/usr/man -> /usr/share/man, etc

[Richard Kettlewell <rjk@sfere.greenend.org.uk>]

I recently installed some packages from potato - e.g. the Libc, some
of the toolchain, etc - on my otherwise largely slink-derived system.

One consequence of this was that the man pages for the new packages
were unavailable, as slink's man(1) didn't know to look in
/usr/share/man as well as /usr/man.

There seems to be a similar change regarding /usr/info and /usr/doc -
and perhaps some other directories that I haven't spotted.

Can someone tell me how this transition is supposed to work?  Why are
there no package dependencies to ensure that it happens smoothly?
