#*******************************************************************************
# buidReleaseInclDocker.yml
#
# Workflow to build a Maiko release that is pushed to github as well as
# Docker images incorporating the release, which are pushed to Docker Hub.
# For linux:  release assets are built/pushed for X86_64, aarch64 and arm7vl and 
#     a multiplatform Docker image is pushed.
# For macOS:  release assets are built/pushed for X86_64. (No aarch64 as yet.)
# For Windows:  not supported
#
# Note release pushed to github automatically includes source code assets
# in tar and zip formats.
