# Usually, sympow has 3 levels of caching: statically distributed in /usr/,

# other users and a shared /var is not compatible with nix's approach, so we

# set VARPREFIX to the read-only $out. This effectively disables shared

# caching. See https://trac.sagemath.org/ticket/3360#comment:36 and sympow's
