Icon: information, question, warning, error or none.
Buttons OK, OK/Cancel, Yes/No, Yes/No/Cancel, with custom labels and a default button.
Monitor selection and window placement.
Windows MessageBox style return codes (-wrc) and a quiet mode.

Usage

MessageBox.exe -t "Hello" -m "This is a message."
MessageBox.exe -t "Info" -m "Line 1\nLine 2\nLine 3"

Store the answer in a variable:
