# largely cribbed from java_stub_template.txt

# Call this program X.  X was generated by an android_device rule
# X may be invoked in many ways:
#   1a) directly by a user, with $0 in the output tree
#   1b) via 'bazel run' (similar to case 1a)
#   2) directly by a user, with $0 in X's runfiles tree
#   3) by another program Y which has a data dependency on X, with $0 in Y's
#   runfiles tree
#   4) via 'bazel test --test_strategy=local'
#   5) by a genrule cmd, with $0 in the output tree
#   6) case 3 in the context of a genrule
#   7) as the first argument to --run_under for a run or test action, with $0 in
#   the output tree - the --blaze_unittest flag identifies this case
#
# For case 1, $0 will be a regular file, and the runfiles tree will be
# at $0.runfiles.
# For case 2 or 3, $0 will be a symlink to the file seen in case 1.
# For case 4, $TEST_SRCDIR should already be set.
# Case 5 is handled like case 1.
# Case 6 is handled like case 3.
