The Dpkg::Conf object can be used to read options from a configuration
file. It can exports an array that can then be parsed exactly like @ARGV.
my $conf = Dpkg::Conf->new(%opts)
Create a new Dpkg::Conf object. Some options can be set through %opts:
if allow_short evaluates to true (it defaults to false), then short
options are allowed in the configuration file, they should be prepended
with a single dash.
@options = $conf->get_options()
Returns the list of options that can be parsed like @ARGV.
Read options from a file. Return the number of options parsed.
Parse options from a file handle. Return the number of options parsed.
$conf->filter(remove => $rmfunc)
$conf->filter(keep => $keepfunc)
Filter the list of options, either removing or keeping all those that
return true when &$rmfunc($option) or &keepfunc($option) is called.
$string = $conf->output($fh)
Write the options in the given filehandle (if defined) and return a string
representation of the content (that would be) written.
