+#!/bin/bash
+# by varacanero@zeromail.org
+# under gpl licence v3
+
+# Usage: 
+
+# * check if wait_for_prompt() is working correctly by running shelr-screencast.sh ~/coding/xdotool/script
+# * in order to get this working, you need sth like this in your .bashrc: 
+#   PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"'
+# * open another terminal, not bigger than 132x43
+# * gain temp. sudo priviledges with "sudo /bin/true" 
+# * start "shelr record"
+# * start this script in another terminal i.e. "./shelr-screencast.sh /home/varac/coding/xdotool/script" 
+# * move mouse focus to shelr window !
+
+# Limitations
+# to query if a window is processing some cmd of is waiting with a shell prompt, 
+# you can't su to another users, cause xprop would not recognize running cmds.
+# you need to run this as the xsession user
+
+
+# for tty backend ~350
