# @description This function ensures dependencies like `git` and `curl` are installed. More specifically, this function will:
#
#     1. Check if `curl`, `git`, `expect`, `rsync`, and `unbuffer` are on the system
#     2. If any of the above are missing, it will then use the appropriate system package manager to satisfy the requirements. *Note that some of the requirements are not scanned for in order to keep it simple and fast.*
#     3. On macOS, the official Xcode Command Line Tools are installed.
