Is there a way to tell automake to not include rules for building .ps files from a .texi?

[Rick Jones]

I have been asked if I was willing to eschew creating the .ps version of 
the netperf manual.  I gather that automake has automagically included 
rules for building netperf.ps from netperf.texi and I am wondering if 
there is a way to ask it to not do that?

thanks,
