generic name for a postscript viewer virtual package ?

[Benoît Rouits <brouits@free.fr>]

Hello list,

I have a Debian package that currently recommends the "evince" package, 
but I would like to make a generic recommendation for any postscript 
viewer. Is there such a virtual package ? or should I enumerate all the 
viewers as recommendation ? (okular, etc...)

Thank you for your help,
 Benoît
