# https://golang.org/issue/45094: 'go mod tidy' now accepts a '-go' flag
# to change the language version in use.
#
# The package import graph used in this test looks like:
#
# m --- a --- b
#             |
#             b_test --- c
#                        |
#                        c_test --- d
#
# The module diagram looks like:
#
# m --- a --- b
# |
# + --- c
# |
# + --- d
#
# Module b omits its dependency on c, and module c omits its dependency on d.
#
# In go 1.15, the tidy main module must require a (because it is direct),
# c (because it is a missing test dependency of an imported package),
# and d (because it is a missing transitive test dependency).
#
# In go 1.16, the tidy main module can omit d because it is no longer
# included in "all".
#
# In go 1.17, the main module must explicitly require b
# (because it is transitively imported by the main module).

cp go.mod go.mod.orig

	# write our version in toolchain lines.
