#    code from. The template will append '-[region_name]' to this bucket name.
#    For example: ./build-s3-dist.sh solutions my-solution v1.0.0
#    The template will then expect the source code to be located in the solutions-[region_name] bucket

#  - trademarked-solution-name: name of the solution for consistency
#
#  - version-code: version of the solution
