# itmux - convinence functions for using iTerm2/tmux integration over ssh.
#
# Usage:
#
#    $ source $0         # Preferably put in your .*shrc
#    $ itmux-ssh <host>
#
# To compile and install the iTerm2-enabled tmux on the remote host, you
# can try issuing:
# 
#    $ itmux-ssh-install <host>
#
# This is an automatic installer tested on Ubuntu Quantal 12.10 If this
# fails, you might have to install it manually.
