Deb supports logical OR.  It looks like:
  Depends: ..., debconf (>= 0.5) | debconf-2.0
What's crude about it?

Debian also has standardized naming, of course.

  Not every package listed on the command line has to be installed;
  you can tell aptitude to do something different with a package by
  appending an "override specifier" to the name of the package. ...
  The following override specifiers are available:
     <package>&m: Mark <package> as having been manually installed.

So 'aptitude install Y&m Z&m; aptitude remove X', or even 'aptitude
remove X Y&m Z&m'.  (There's some way to access this stuff in the
interactive UI, I believe involving the 'm' key, but I'm feeling too
elite to read any more of the manual right now.)

'aptitude install openoffice.org-writer'.  See also Depends vs.
Recommends vs. Suggests.
