# listed in the sha256sums-unsigned-build.txt file to full update
# mar files. After code signing the dmg files, this script can be used
# to update the mar files.

# as 15.14. The version in Debian Jessie (9.20) is not recent enough.
# It is possible to install the p7zip-full package from Debian testing,
# or build p7zip from sources:
#  $ p7zipdir=/some_directory/p7zip
#  $ mkdir $p7zipdir
#  $ cd $p7zipdir
#  $ wget http://snapshot.debian.org/archive/debian/20160417T044336Z/pool/main/p/p7zip/p7zip_15.14.1%2Bdfsg.orig.tar.xz
