## set up some variables to ensure that we're operating strictly in
## the tests, not system-wide:

mkdir -p "$TESTDIR"/tmp
TEMPDIR=$(mktemp -d "${TMPDIR:-$TESTDIR/tmp}/monkeyspheretest.XXXXXXX")

mkdir "$TEMPDIR"/bin

# Use the local copy of executables first, instead of system ones.
# This should help us test without installing.
