diff-ignore - perl regexp to filter out files for the diff

perl regular expression to match files you want filtered out of the list of files for the diff.This is very helpful in cutting out extraneous files that get included in the diff, e.g. if you maintain your source in a revision control system and want to use a checkout to build a source package without including the additional files and directories that it will usually contain (e.g. CVS, .cvsignore, .svn/). The default regexp is already very exhaustive, but if you need to replace it, please note that by default it can match any part of a path, so if you want to match the begin of a filename or only full filenames, you will need to provide the necessary anchors (e.g. '(^|/)', '($|/)') yourself. Optional. Type uniline.

extend-diff-ignore - Perl regexp to extend the diff-ignore setup

The perl regular expression specified will extend the default regular expression associated to diff-ignore by concatenating "|regexp" to the default regexp. This option is convenient to exclude some auto-generated files from the automatic patch generation. Optional. Type uniline.

compression - Specify the compression to use for created tarballs and diff files.

The default is xz for formats 2.0 and newer, and gzip for format 1.0. xz is only supported since dpkg-dev 1.15.5. Optional. Type enum. choice: 'gzip', 'bzip2', 'lzma', 'xz'.

upstream_default value :

xz

compression-level - Compression level to use.

Default compression level is 9 for gzip and bzip2, 6 for xz and lzma. Optional. Type enum. choice: '1', '2', '3', '4', '5', '6', '7', '8', '9', 'best', 'fast'.
