Just because testing is boring, and triggers are arcane, I'm  
entertaining myself
with cross-arch triggers.

These are triggers that fire on package N __AND__ A compound
dependencies.

Mostly seems to work, dunno yet, although I'll have to fiddle a bit  
with negated
compound N.A conditions, as in

	%triggerin     b -- !test-triggers-a.noarch
	  echo "--- triggerin(bA)      arg $1 $2 ..."

i.e. a trigger that will fire on all packages __EXCEPT__ test- 
triggers.noarch,
aka a package install fork bomb ;-)

I'll append my current test-triggers spec file, in case anyone else  
wants to have
some fun. I've a bit more to do for RPMTAG_PROVIDENAME and  
RPMTAG_DIRNAMES
triggers, todo++.

Enjoy!
