# Create source tarball from git repo. Takes a branch (not a commit or tag)
# as an argument! Warning, this is different from all the other git2tarxz
# scripts on SBo!

# Note that this script doesn't need to be run as root. It does need to
# be able to write to the current directory it's run from.

# Takes one optional argument, which is the *branch* to create a
# tarball of. With no arg, this is used:
BRANCH=${1:-v5.13.1}
