# ABSTRACT: Temp Dir support for Alien::Build
our $VERSION = '2.29'; # VERSION
# problem with vanilla File::Temp is that is often uses
# as /tmp that has noexec turned on. Workaround is to
# create a temp directory in the build directory, but
# we have to be careful about cleanup. This puts all that
# (attempted) carefulness in one place so that when we
# later discover it isn't so careful we can fix it in
# one place rather thabn alllll the places that we need
# temp directories.
