# logika kako slijedi:
# imamo popis testova i akcija koje ce se izvrsiti svakog testa
# ("queuetab" datoteka)
#
# akcije se izvrsavaju redoslijedom iz popisa
#
# neke akcije imaju dio koji se izvrsava prije i dio koji se izvrsava nakon
# upgradea, svaka takva akcija dodaje svoj post-upgrade dio akcije u
# zasebni red akcija, i onda se to izvrsava nakon upgradea na isti nacin
# kao glavni red akcija.

# queuetab file format:
# test		action
#
# eg. "pkg xinetd-cn lt 2:0     do_xinetd" means:
# if there is a version of xinetd-cn lower than 2:0 installed,
# invoke do_xinetd function
# generic tests:
# pkg  tests if a package is installed, optional arguments like
#      dpkg --compare-versions

# Sanitize environment
