dpkg-trigger - a package trigger utility
dpkg-trigger is a tool to explicitly activate triggers and check
for its support on the running dpkg.
This can be used by maintainer scripts in complex and conditional
situations where the file triggers, or the declarative activate
triggers control file directive, are insufficiently rich. It can also
be used for testing and by system administrators (but note that the
triggers won't actually be run by dpkg-trigger).
Unrecognised trigger name syntaxes are an error for dpkg-trigger.
Check if the running dpkg supports triggers (usually called from a
postinst). Will exit 0 if a triggers-capable dpkg has run, or 1 with
an error message to stderr if not. Normally, however, it is better just to
activate the desired trigger with dpkg-trigger.
