# Parameters:
#  - source-bucket-base-name: Name for the S3 bucket location where the template will source the Lambda
#    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
#
#  - solution-name: name of the solution for consistency
#
#  - version-code: version of the package
