Bug#807585: [PATCH] pristine-gz: add XDELTA_PROGRAM build parameter
Package: pristine-tar
Version: 1.33
Tags: patch
The XDELTA_PROGRAM build parameter may be used to define the xdelta
binary to be used by pristine-tar. This patch increases compatibility
with many non-Debian systems that do ship xdelta 3 by default.
