# @description This function ensures Homebrew is installed and available in the `PATH`. It handles the installation of Homebrew on both **Linux and macOS**.
|
|
# It will attempt to bypass sudo password entry if it detects that it can do so. The function also has some error handling in regards to various
|
|
# directories falling out of the correct ownership and permission states. Finally, it loads Homebrew into the active profile (allowing other parts of the script
|
|
# to use the `brew` command).
|
|
#
|
|
# With Homebrew installed and available, the script finishes by installing the `gcc` Homebrew package which is a very common dependency.
