Created a branch for it:


Review welcome.  Note that the "installed-by" files work differently
than documented.  I have opted for keeping the behaviour and correcting
the documentation.

Done.  This will probably come in handby due to the next item and the
following call pattern.

 dh_install -ppkg foo bar
 dh_install --remaining

Did a prototype for dh_installman, which seems to be working (with the
above CAVEAT)

NB: Due to how this is implemented, the "install-by" files will get
duplicates when you do:

  dh_install -a # first copy
  dh_install -i # second copy

It does not appear to be a problem atm., so I have left it at that.

Still lacking.

I might do the upload "soon" (before the release), but lets keep the
mass-rebuild for post-freeze to avoid diverting peoples attention.
