-=head1 NAME
-
-Dpkg::Vendor::Default - default vendor object
-
-=head1 DESCRIPTION
-
-A vendor object is used to provide vendor specific behaviour
-in various places. This is the default object used in case
-there's none for the current vendor or in case the vendor could
-not be identified (see Dpkg::Vendor documentation).
-
-It provides some hooks that are called by various dpkg-* tools.
-If you need a new hook, please file a bug against dpkg-dev and explain
-your need. Note that the hook API has no guaranty to be stable over an
-extended period. If you run an important distribution that makes use
-of vendor hooks, you'd better submit them for integration so that
-we avoid breaking your code.
-
-=head1 FUNCTIONS
-
-=over 4
-
-=item $vendor_obj = Dpkg::Vendor::Default->new()
-
-Creates the default vendor object. Can be inherited by all vendor objects
-if they don't need any specific initialization at object creation time.

-}
-
-=item $vendor_obj->run_hook($id, @params)
-
-Run the corresponding hook. The parameters are hook-specific. The
-supported hooks are:
-
-=over 8
-
-=item before-source-build ($srcpkg)
-
-The first parameter is a Dpkg::Source::Package object. The hook is called
-just before the execution of $srcpkg->build().
-
-=item keyrings ()
-
-The hook is called when dpkg-source is checking a signature on a source
-package. It takes no parameters, but returns a (possibly empty) list of
-vendor-specific keyrings.
-
-=item register-custom-fields ()
-
-The hook is called in Dpkg::Control::Fields to register custom fields.
-You should return a list of arrays. Each array is an operation to perform.
-The first item is the name of the operation and corresponds
-to a field_* function provided by Dpkg::Control::Fields. The remaining
-fields are the parameters that are passed unchanged to the corresponding
-function.
-
-Known operations are "register", "insert_after" and "insert_before".
-
-=item post-process-changelog-entry ($fields)
-
-The hook is called in Dpkg::Changelog to post-process a
-Dpkg::Changelog::Entry after it has been created and filled with the
-appropriate values.
-
-=item update-buildflags ($flags)
-
-The hook is called in Dpkg::BuildFlags to allow the vendor to override
-the default values set for the various build flags. $flags is a
-Dpkg::BuildFlags object.
