    # INSTRUCTIONS:

    # 1) Copy and edit this file:
    #
    # $ cp node_modules/genericsuite-be-scripts/scripts/aws/update_additional_envvars.sh ./scripts/aws/
    # $ vi scripts/aws/update_additional_envvars.sh

    # 2) Add your additional environment variables replacements here as:
    #
    # perl -i -pe"s|ENVVAR_NAME_placeholder|${ENVVAR_NAME}|g" "${CONFIG_FILE}"
    #
    # ... replacing "ENVVAR_NAME" with the name of the environment variable

    # 3) Add the additional environment variables to the ".env" file:
    #
    # ENVVAR_NAME=value
    #
    # ... replacing "ENVVAR_NAME" with the name of the environment variable and ENVVAR_VALUE with its value.

    # 4) Add the additional environment variables to the "scripts/aws_big_lambda/template-sam.yml" file in the section "APIHandler > Properties > Environment > Variables". E.g.
    #      .
    #      .
    #   APIHandler:
    #          .
    #          .
    #      Properties:
    #             .
    #             .
    #        Environment:
    #          Variables:
    #            ENVVAR_NAME: ENVVAR_VALUE
    #                  .
    #                  .
    # ... replacing "ENVVAR_NAME" with the name of the environment variable

    # 5) If you're using the Chalice framework, add the additional environment variables to the ".chalice/config-example.json" file, in the main "environment_variables" section. E.g.
    #
    #    {
    #       "version": "2.0",
    #             .
    #             .
    #       "environment_variables": {
    #                .
    #                .
    #          "ENVVAR_NAME": "ENVVAR_NAME_placeholder"
    #       },
    #       "stages": {
    #             .
    #             .
    #
    # ... replacing "ENVVAR_NAME" with the name of the environment variable (in both places).
