# Submodule tests

# Repository A with submodules defined  (repo_submodules)
#   .gitmodules file points to Repository I
# Repository B forked from A that has newer commits (repo_submodules_newer)
#   .gitmodules file points to Repository II instead of I
#   .gitmodules file also points to Repository III
# Repository I for submodule1 (repo_submodule1)
#   Has 1 file checked in
# Repository II forked from I that has newer commits (repo_submodule1_newer)
#   Has 2 files checked in
# Repository III for a second submodule (repo_submodule2)
#   Has 1 file checked in
