# Description: This program is a Graphical User Interface (GUI) 
#              Control Centre for LTP. The Control Centre provides 
#              functionality to Compile, Execute and View Results of
#              LTP test cases.
#              
# Author:      Manoj Iyer - manjo@mail.utexas.edu
#
# Thanks:      Jim Choate - For suggesting the use of dialog command.
#
# History:     March 26 2003 - Created.
#
#	       March 28 2003 - Removed gauges and put make commands in foreground.
#	                     Robbie Williamson - robbiew@us.ibm.com
#
#	       March 31 2003 - Made scenario menu creation dynamic and code 
#                              to pull the test descriptions from the scenario files.
#                            Robbie Williamson - robbiew@us.ibm.com
#
#	       April 17 2003 - Added menu selection to list contents of selected
#			       scenario file.
#			     Robbie Williamson - robbiew@us.ibm.com
#
#	       April 23 2003 - Added PID to results filename.
#			     - Added code to allow users to redirect output and
#                              specify test execution duration.
#			     Robbie Williamson - robbiew@us.ibm.com
#
#	       April 30, 2003 - Recoded results display to allow selection
#				of results file.
#			      - Created variable to hold results filename
#		 	      - Added time to results filename.
