       ucfr  -	Update	Configuration  File Registry:  associate packages with
       configuration files

       ucfr [options]  

       Where Package is the package associated	with  the  configuration  file
       (and,  in some sense, its owner), and Path to configuration file is the
       full path to the location (usually under /etc) where the  configuration
       file lives, and is potentially modified by the end user.

       This  script  maintains	an association between configuration files and
       packages, and is meant to help provide facilities  that	dpkg  provides
       conffiles  for configuration files and not shipped in a Debian package,
       but handled by the postinst by ucf instead. This script is  idempotent,
       associating  a package to a file multiple times is not an error.  It is
       normally an error to try to associate a file which is  already  associ
       ated  with  another  package,  but this can be over ridden by using the
       --force option.

       -h, --help
	      Print a short usage message

       -n, --no-action
	      Dry run. Print the actions that would be taken if the script  is
	      invoked, but take no action.

       -d [n], --debug [n]
	      Set the debug level to the (optional) level n (n defaults to 1).
	      This turns on copious debugging information.

       -p, --purge
	      Removes all vestiges of the association between the named  pack
	      age  and	the configuration file from the registry. The associa
	      tion must already exist; if the configuration file is associated
	      with  some  other  package,  an error happens, unless the option
	      --force is also given. In that case, the	any  associations  for
	      the configuration file are removed from the registry, whether or
	      not the package name matches. This action is idempotent,	asking
	      for  an  association to be purged multiple times does not result
	      in an error, since attempting to remove an non-existent associa
	      tion is silently ignored unless the --verbose option is used (in
	      which case it just issues a diagnostic).

       -v, --verbose
	      Make the script be very verbose  about  setting  internal  vari

       -f, --force
	      This  option  forces operations requested even if the configura
	      tion file in consideration is owned  by  another	package.  This
	      allows  a  package  to  hijack a configuration file from another
	      package, or to purge the association between the file  and  some
	      other package in the registry.

       --state-dir /path/to/dir
	      Set  the	state directory to /path/to/dir instead of the default
	      /var/lib/ucf.  Used mostly for testing.

       The most common case usage is pretty simple: a single  line  invocation
       in  the postinst on configure, and another single line in the postrm to
       tell ucfr to forget about the association with the  configuration  file
       on  purge  (using  the  --purge option) is all that is needed (assuming
       ucfr is still on the system).

       /var/lib/ucf/registry, and /var/lib/ucf/registry.X, where X is a  small
       integer, where previous versions of the registry are stored.


       If the package foo wants to use ucfr to associate itself with a config
       uration file foo.conf, a simple invocation of ucfr in the postinst file
       is all that is needed:

       ucfr foo /etc/foo.conf

       On  purge,  one	should tell ucf to forget about the file (see detailed
       examples in /usr/share/doc/examples):

       ucfr --purge foo /etc/foo.conf

       ucf(1), ucf.conf(5).
