# SYNOPSIS
#
#   AX_PROG_ROBOT([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])

# DESCRIPTION
#
#   This macro searches for the "robot" command from the Robot Framework and
#   sets the variable "ROBOT" to the name of the application and the
#   "ROBOT_VERSION" variable to the version of the Robot Framework. When
#   robot is found sets the "HAS_ROBOT" to "yes", otherwise to "no".
#
