# @description
#   This script will ensure [Task](https://github.com/go-task/task) is up-to-date
#   and then run the `start` task which is generally a good entrypoint for any repository
#   that is using the Megabyte Labs templating/taskfile system. The `start` task will
#   ensure that the latest upstream changes are retrieved, that the project is
#   properly generated with them, and that all the development dependencies are installed.
