# Set terminal window and tab/icon title
#
# usage: title short_tab_title [long_window_title]
#
# See: http://www.faqs.org/docs/Linux-mini/Xterm-Title.html#ss3.1
# Fully supports screen, iterm, and probably most modern xterm and rxvt
# (In screen, only short_tab_title is used)
# Limited support for Apple Terminal (Terminal can't set window and tab separately)

# This is the title() function taken directly from oh-my-zsh
# https://github.com/ohmyzsh/ohmyzsh/blob/c44b99e901d7ef58f60247995152de1b937e2e9c/lib/termsupport.zsh
