This package uses dbs (package name 'dbs') for patch management.  All patches
are stored under debian/patches directory. They can be applied using the
following command:
   
   % debian/rules patch

Patches can be edited using the following command:

   % dbs-edit-patch <patch name>

<patch name> should not include path name. After this command a directory with
the same name will be created under /tmp. You can then edit subdirectory 'src'.
After making changes run script dbs-update-patch (in patch subdirectory, under
/tmp) to update the patch. If patch with given name does not exist yet, it will
be created.

NOTE: dbs applies patches in alphanumerical order, so it is better to start
patch names with a number.

To disable some patches just remove them or move away from debian/patches.

Package can be updated to new upstream version using "uscan" from the
'devscripts' package. Just run "uscan" in package source directory.
