# Argument one: name of the robot wrapper script in the form <Strategy>-<RobotName>-<Team>.robot
# <Strategy>, <RobotName> and <Team> must not contain hyphens, any kind of slashes, the at symbol or the ampersand
# Argument two: <rtb-team home>
# <rtb home> must not contain the at symbol, the ampersand or the character "|"
# This script will create a file named <robot name>.robot that assumes that /tmp/<robot name>.log is the only log file used
# Argument three: Template file can contain the following sequences, that will be replaced:
# @STRATEGY@, @ROBOTNAME@, @TEAM@, @RTBHOME@
# If the third argument is not present, take the included HERE document configuration template 
# Will create file called like argument one
