+#!/bin/bash
+# This bash script is designed to be called from a command prompt in your      #
+# favorite tiling window-manager or desktop environment or from any graphical  #
+# program running in X.                                                        #
+# It handles wrapping the command you give it as an argument in X, that is     #
+# to say in your favorite terminal emulator. By default it also wraps your     #
+# command in a tmux terminal, either by creating a new session, or by adding a #
+# window to a pre-existing session:                                            #
+#                                                                              #
+#                       Terminal [ Tmux ( Command ) ]                          #
+#                                                                              #
+# Called without argument, it will start the command $DEFAULTSHELL. If a       #
+# terminal window has already been opened, it will NOT create a new one, but   #
+# add instead a new tmux window in the current tmux session, or if no session  #
+# is started, this script will start a new session.                            #
