+## 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.
