# It’s mostly just for fun but it’s currently used to order snacks (See “Buy groceries with PowerShell”-post) when a TV Show I follow starts/ends soon.
# A short post about these functions are available at:
# https://p0wershell.com/?p=2911
# If these doesn’t work, feel free to post a comment on the blog and I’ll try to fix them!
# Edit: Site changed so these functions needed to be updated accordingly.
