=head1 NAME
Dpkg::Vendor - get access to some vendor specific information
=head1 DESCRIPTION
The files in /etc/dpkg/origins/ can provide information about various
vendors who are providing Debian packages. Currently those files look like
this:
Vendor: Debian
Vendor-URL: http://www.debian.org/
Bugs: debbugs://bugs.debian.org
The file should be named according to the vendor name.
=head1 FUNCTIONS
=over 4
=item $fields = Dpkg::Vendor::get_vendor_info($name)
Returns a Dpkg::Control object with the information parsed from the
corresponding vendor file in /etc/dpkg/origins/. If $name is omitted,
it will use /etc/dpkg/origins/default which is supposed to be a symlink
to the vendor of the currently installed operating system. Returns undef
if there's no file for the given vendor.
=cut
sub get_vendor_info(;$) {
my $vendor = shift || "default";
my $file = get_vendor_file($vendor);
return undef unless $file;
my $fields = Dpkg::Control::Hash->new();
$fields->load($file) || error(_g("%s is empty"), $file);
return $fields;
}
=item $name = Dpkg::Vendor::get_vendor_file($name)
Check if there's a file for the given vendor and returns its
name.
=cut
sub get_vendor_file(;$) {
my $vendor = shift || "default";
my $file;
my @tries = ($vendor, lc($vendor), ucfirst($vendor), ucfirst(lc($vendor)));
if ($vendor =~ s/\s+/-/) {

}
foreach my $name (@tries) {
$file = "$origins/$name" if -e "$origins/$name";
}
return $file;
}
=item $name = Dpkg::Vendor::get_current_vendor()
Returns the name of the current vendor. If DEB_VENDOR is set, it uses
that first, otherwise it falls back to parsing /etc/dpkg/origins/default.
If that file doesn't exist, it returns undef.
=cut
sub get_current_vendor() {

$f = get_vendor_info($ENV{'DEB_VENDOR'});
return $f->{'Vendor'} if defined $f;
}
$f = get_vendor_info();
return $f->{'Vendor'} if defined $f;
return undef;
}
=item $object = Dpkg::Vendor::get_vendor_object($name)
Return the Dpkg::Vendor::* object of the corresponding vendor.
If $name is omitted, return the object of the current vendor.
If no vendor can be identified, then return the Dpkg::Vendor::Default
object.
=cut

=item Dpkg::Vendor::run_vendor_hook($hookid, @params)
Run a hook implemented by the current vendor object.
