I just added such an option, for the moment only for potential-cross-conflicts:

  -isd <directory>

will place in <directory> files containing the installationsets (i.e., the
solution found by dose-debcheck). The files are named as in the regular output
directory (package_1=version1_package2=version2). The files contain lines
in the format package=version.
