-## ssh conservative $TERM value helper
-
-Due to inconsistency of 256 color terminal support across
-terminal applications, it may be desirable to force the
-$TERM value to it's -256color variant.
-
-For example, this is often accomplished in tmux by means
-of adding the following to a tmux.conf file:
-
-    set -g default-terminal "screen-256color"
-
-Unfortunately, remote hosts accessed via ssh may not have
-the requisite terminfo files, and may not even allow the
-user to supply them, as is often the case with network
-equipment and other appliances accessible via ssh.
-
-This helper strips the -256color suffix and exports a
-regular 'screen' or 'xterm' $TERM value when setting up
-a ssh connection.
