=over 2

Normally, the script presents the information in a human readable
tabular format, but that may be harder for a machine to parse. With
this option, the output is a compact, colon separated line, with no
dividers, headers, or footer.

=item B<--state-dr> dir

=over 2

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

=head1 DESCRIPTION

This script takes a set of arguments, each of which is a package or a
path to a configuration file, and outputs the associated package, if
any, if the file exists on disk, and whether it has been modfied by te
user.  The output is either a human readable tabular form, or a
compact colon-separated machine friendly format.

This script can potentially be used in package C<postinst> scripts
during purge to query the system for configuration files that may
still exist on the system, and whether these files have been locally
modified by the user -- assuming that the package registered all the
configuration files with B<ucf> using C<ucfr>.

=head1 INTERNALS

=head2 Class Methods

All class methods mediate access to class variables.  All class
methods can be invoked with zero or one parameters. When invoked with
the optional parameter, the class method sets the value of the
underlying class data.  In either case, the value of the underlying
variable is returned.

=cut

=head1 Class ucf

This is a combination view and controller class that mediates between
the user and the internal model classes.

=head2 new

This is the constructor for the class. It takes a number of optional
parameters. If the parameter B<Colons> is present, then the output
will be compact. The parameters B<DEBUG> and B<VERBOSE> turn on
additional diagnostics from the script.

arguments, and queries the on disk databases, determines of the files
exist, and have been modified.

This routine generates a nicely formatted report based on the
information gathered during the processing. There are two kinds of
reports, the first being a user friendly tabular form, the second
