# This script is run in CI and support both pull request and commit modes. So
# it can be used also on commits to the tree or on tags.
# The following options are supports:
# -p  start the script for pull requests
# -m  matrix node number, for example 3 on a 5 node matrix
# -M  total number of nodes in the matrix
# -b  base branch
# -r  the remote to rebase on
#
# The script can be run locally using for exmaple:
# ./scripts/ci/run_ci.sh -b master -r upstream  -p
