diff2patches man page
diff2patches — Extract non-debian/ patches from .diff.gz files
Extracts patches from .diff.gz which apply to files outside the “debian/” directory scope. A patch is created for each modified file. Each patch is named according to the path of the modified file, with “/” replaced by “___”, and an extension of “.patch”.
Extract patches from filename which apply outside the “debian/” directory.
Output help information and exit.
Output version information and exit.
Existence of this file is tested before any patch is extracted.
Patches are extracted to one of these directories. “debian/patches/” is preferred, if it exists. If DEB_PATCHES is present in the environment, it will override this behavior (see “Environment Variables” section below).
When defined and points to an existing directory, patches are extracted in that directory and not under “debian/” nor “debian/patches/”.
