.PARAMETER Location
	The location to get weather from.
	Can be "paris", "muc" (airport code), "@becca.ooo", "94107", or "moon" for the moon phase.

.PARAMETER Imperial
	Aliased to "USCS".
	Forces imperial units.
	Units are normally auto-detected from the location.
	If both -Metric and -Imperial are specified, metric units are used.

.PARAMETER Metric
	Forces metric units.
	Units are normally auto-detected from the location.
	If both -Metric and -Imperial are specified, metric units are used.

.PARAMETER Simple
	Non-colored output.
	Normally, this function loads Kernel32.dll and changes the console mode to display the ANSI/VT100 color formatting sequences that wttr.in uses. -Simple fetches a text-only version and doesn't load any DLLs or anything.
	Will prevent a slight delay on the first call per shell.

.PARAMETER Abbreviate
	Only display the first few lines.

.PARAMETER Today
	Only displays the weather for today.

.PARAMETER Tomorrow
	Only displays the weather for tomorrow.

.PARAMETER DayAfterTomorrow
	Only displays the weather for the day after tomorrow.
