name: Build and Test

# Builds and tests on all combinations of OS, build type, and library type.
#
# Runs when a pull request is opened, or triggered from other workflows.
#
# If triggered from another workflow, optionally attaches release artifacts to a
# release, since those artifacts can't be accessed from another workflow later.
#
# If triggered from another workflow, optionally initiates another workflow
# afterward, allowing for chaining of workflows.  This capability is used in the
# release process, so that the relatively-complex build_and_test workflow can be
# reused in the middle of the release process without duplication.
#
# Can also be run manually for debugging purposes.
