# Usage: ./colour.pl
#
# This is an example of including ANSI SGR escapes in the status lines.
# EscStatus recognises ANSI escapes as taking no width.  You can create the
# escapes any way you want, here Term::ANSIColor is used to do it by name
# (instead of the escape code numbers).
#
# Obviously how such escapes actually display depends on the terminal.  If
# it's a non-ANSI terminal, or it's only black-and-white, or something, then
# printing such escapes might be bad.
