-=head1 NAME
-
-Dpkg::Vendor - get access to some vendor specific information
-
-=head1 DESCRIPTION
-
-The files in $Dpkg::CONFDIR/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
-
-If the vendor derives from another vendor, the file should document
-the relationship by listing the base distribution in the Parent field:
-
-  Parent: Debian
-
-The file should be named according to the vendor name.
-
-=head1 FUNCTIONS
-
-=over 4
-
-=item $dir = Dpkg::Vendor::get_vendor_dir()
-
-Returns the current dpkg origins directory name, where the vendor files
-are stored.
-
-=cut
-
-sub get_vendor_dir {
-    return $origins;
-}
-
-=item $fields = Dpkg::Vendor::get_vendor_info($name)
-
-Returns a Dpkg::Control object with the information parsed from the
-corresponding vendor file in $Dpkg::CONFDIR/origins/. If $name is omitted,
-it will use $Dpkg::CONFDIR/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.

-=item $name = Dpkg::Vendor::get_vendor_file($name)

-Check if there's a file for the given vendor and returns its

-
-=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 $Dpkg::CONFDIR/origins/default.
-If that file doesn't exist, it returns undef.
