# EP_TRIGGER_BEGIN replaces $c->{session_init}

#  Invoked each time a new repository is needed (generally one per
#  script invocation.) $repository is a repository object that can be used
#  to store any values you want. To prevent future clashes, prefix
#  all of the keys you put in the hash with repository.
#
#  If $offline is non-zero, the repository is an `off-line' repository, i.e.
#  it has been run as a shell script and not by the web server.
