NAME
Debconf::Client::ConfModule - client module for ConfModules
SYNOPSIS

version('2.0');

input("medium", "foo/bar");
my @ret=go();
if ($ret[0] == 30) {

DESCRIPTION
This is a module to ease writing ConfModules for Debian's configuration
management system. It can communicate with a FrontEnd via the debconf
protocol (which is documented in full in the debconf_specification in
Debian policy).
The design is that each command in the protocol is represented by one
function in this module (with the name lower-cased). Call the function
and pass in any parameters you want to follow the command. If the
function is called in scalar context, it will return any textual return
code. If it is called in list context, an array consisting of the
numeric return code and the textual return code will be returned.
This module uses Exporter to export all functions it defines. To import
everything, simply import ":all".
import
Ensure that a FrontEnd is running. It's a little hackish. If
DEBIAN_HAS_FRONTEND is set, a FrontEnd is assumed to be running. If
not, one is started up automatically and stdin and out are connected
to it. Note that this function is always run when the module is
loaded in the usual way.
stop
The frontend doesn't send a return code here, so we cannot try to
read it or we'll block.
AUTOLOAD
Creates handler functions for commands on the fly.
