Needs-Info: debfiles

Tag: dpatch-build-dep-but-no-patch-list
Type: warning
Info: Using dpatch requires you to explicitly list all patches you want
 to apply in debian/patches/00list. This package build-depends on dpatch,
 but does not provide a patch list.
 .
 You should either remove the dpatch build dependency or add a patch
 list.

Tag: dpatch-index-references-non-existent-patch
Type: error
Info: In the 00list file listing all your dpatches, you referenced a file
 that does not exist. This will lead to a fatal error when calling dpatch.

Tag: dpatch-missing-description
Type: warning
Info: dpatch files should carry a description of the function of the included
 patch. Description lines start with "## DP:".

Tag: quilt-build-dep-but-no-series-file
Type: warning
Info: Using quilt requires you to explicitly list all patches you want
 to apply in debian/patches/series. This package build-depends on quilt,
 but does not provide a patch list.
 .
 You should either remove the quilt build dependency or add a series
 file.

Tag: quilt-series-but-no-build-dep
Type: warning
Info: The package contains a debian/patches/series file usually used by
 quilt to apply patches at build time, but quilt is not listed in the
 build dependencies.
 .
 You should either remove the series file if it's effectively not useful
 or add quilt to the build-dependencies if quilt is used during the build
 process.
 .
 If you don't need quilt during build but only during maintenance work,
 then you can override this warning.

Tag: quilt-patch-with-non-standard-options
Type: warning
Info: The quilt series file contains non-standard options to apply some of
 the listed patches. Quilt uses '-p1' by default if nothing is specified
 after the name of the patch and the current series file specify something
 else for some of the patches listed.
 .
 For compatibility with the source "3.0 (quilt)" source package format,
 you should avoid using any option at all and make sure that your patches
 apply with "-p1". This can be done by refreshing all patches like this:
 quilt pop -a; while quilt push; do quilt refresh -pab; done

Tag: quilt-series-references-non-existent-patch
Type: error
Info: In the series file listing all your quilt patches, you referenced a
 file that does not exist. This will lead to a fatal error when calling quilt.

Tag: patch-modifying-debian-files
Type: error
Info: A patch stored in debian/patches/ should never modify files
 in the debian directory (even when it's only creating new files) because
 the debian directory is always directly provided by the Debian packaging.
 And you shouldn't have to modify what you choose to provide in the first
 place.
 .
 If the patch provides a new file (say a manual page), place that file
 in the upstream directory hierarchy as if it was ready to be submitted.

Tag: patch-system-but-direct-changes-in-diff
Type: warning
Info: The package uses a patch-system, but the Debian diff.gz contains changes
 made on files without being separated out in a patch.

Tag: more-than-one-patch-system
Type: warning
Info: The build-dependencies list more than one patch system and it's
 unlikely that you need both at the same time.
 .
 Currently lintian knows only dpatch and quilt.
