=head1 NAME
dh_auto_configure - automatically configure a package prior to building
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_auto_configure> [S<I<debhelper options>>] [S<B<--> I<params>>]
=head1 DESCRIPTION
dh_auto_configure is a debhelper program that tries to automatically
configure a package prior to building. It looks for and runs a ./configure
script, Makefile.PL, or Build.PL. A standard set of parameters is
determined and passed to the program that is run. If no program to run is
found, dh_auto_configure will exit without doing anything.
This is intended to work for about 90% of packages. If it doesn't work,
you're encoruaged to skip using dh_auto_configure at all, and just run
./configure or its equivilant manually.
=head1 OPTIONS
=over 4
=item B<--> I<params>
Pass "params" to the program that is run. These can be used to suppliment
or override the standard parameters that dh_auto_configure passes.
