# This test illustrates the relationship between the 'all' pattern and
# the dependencies of the main module.

# The package import graph used in this test looks like:
#
# main --------- a --------- b
# |              |
# |              a_test ---- c
# |                          |
# |                          c_test ---- d
# |
# main_test ---- t --------- u
#                |
#                t_test ---- w
#                            |
#                            w_test ---- x
#
# main/testonly_test ---- q --------- r
#                         |
#                         q_test ---- s
#
# And the module dependency graph looks like:
#
# main --- a.1 ---- b.1
#  \   \    \
#   \   \    c.1 -- d.1
#    \   \
#     \    t.1 ---- u.1
#      \    \
#       \    w.1 -- x.1
#        \
#          q.1 ---- r.1
#           \
#            s.1
