 $ man run-mailcap
 $ dpkg -s $(dpkg -S $(which run-mailcap) | cut -d : -f 1) | grep ^Priority
 Priority: standard

          These packages provide a reasonably small but not too limited
          character-mode system.  This is what will be installed by default
          if the user doesn't select anything else.  It doesn't include
          many large applications.

 Depend on postscript-viewer and mime-support.

 Actually the method that _is_ available is rather good, and per-user
 configurable, unlike alternatives.

 I object.
