NAME

       deb-triggers - package triggers

SYNOPSIS

       triggers

DESCRIPTION

       A  package  declares its relationship to some trigger(s) by including a
       triggers file in  its  control  archive  (i.e.  DEBIAN/triggers  during
       package creation).

       This  file  contains  directives,  one  per  line. Leading and trailing
       whitespace and everything after  the  first  #  on  any  line  will  be
       trimmed, and empty lines will be ignored.

       The trigger control directives currently supported are:

            interest trigger-name

            Specifies that the package is interested in the named trigger. All
            triggers in which a package is interested  must  be  listed  using
            this directive in the triggers control file.

            activate trigger-name

            Arranges  that  changes  to this package’s state will activate the
            specified trigger. The trigger will be activated at the  start  of
            the following operations: unpack, configure, remove (including for
            the benefit of a conflicting package), purge and deconfigure.

            If this package disappears during the unpacking of another package
            the  trigger  will  be  activated  when the disappearance is noted
            towards the end of the unpack. Trigger processing, and  transition
            from  triggers-awaited  to  installed, does not cause activations.
            In the case of unpack, triggers mentioned in both the old and  new
            versions of the package will be activated.

       Unknown  directives are an error which will prevent installation of the
       package.
