# Poor-man's tool to bump the onosproject dependencies for a project:
#   1) "go get -u" on the dependencies with the new tag
#   2) create a branch
#   3) push to git

# The tool requires the user to have the authorization to:
#   1) push tag to the upstream repo

# Also, the following conditions must be met:
#   1) repo must have upstream (or origin) remote push enabled via ssh

# If no version is given use "latest" - this will get the latest tagged release of
# the go module, which is the whole point of running the procedure. To get the
# most recent non-tagged versions in git, use "master". To get older versions use
# a version number e.g. v0.6.0, but this will be applied across all onosproject modules
version=${VERSION:-"latest"}
