=cut

use strict;

=head1 SYNOPSIS

B<octave-deps> [S<I<debhelper options>>]

=head1 DESCRIPTION

octave-deps is a debhelper-like program that is responsible for generating
the ${octave:Depends} substitutions and adding them to substvars files.

If you use this program, your package must build-depend on octave2.1-headers
(>= 2.1.65).

init ();

my $octcfg = 'octave-config';
my $octpkg = 'octave2.1';

# The current Octave version
my $octver = `$octcfg --version 2>&1`
	or die "Command $octcfg not found";
chomp $octver;
  
foreach my $package (@{$dh{DOPACKAGES}}) {

	delsubstvar($package, "octave:Depends");
	addsubstvar($package, "octave:Depends", $octpkg, ">= $octver");

}
