# This test illustrates a case where downgrading one module may upgrade another.
# Compare to the downcross2 test case in cmd/go/internal/mvs/mvs_test.go.
# The initial package import graph used in this test looks like:
#
# a ---- b ---- d
#
# The module dependency graph originally looks like:
#
# a ---- b.2 ---- d.2
#
# b.1 ---- c.1
#
# If we downgrade module d to version 1, we must downgrade b as well.
# If that downgrade selects b version 1, we will add a new dependency on module c.
