# Description:  This script can be used to the tests in the LTP test suite
#
# Authors:      Manoj Iyer - manjo@mail.utexas.edu
#               Robbe Williamson - robbiew@us.ibm.com
#               
# History:      Oct 07 2003 - Modified - Manoj Iyer
#               - use functions
#               - clean up on script exit
#               - error checking etc.
#                
#               Oct 08 2003 - Modified - Manoj Iyer
#               - fixed bug in creating results directory
#               - all checks should be enlclosed in " " to avoid bash error
#               - exit with error if pan is not found in pan directory
#
#               Jul 22 2007 - Modified - Ricardo Salveti de Araujo
#               - added support to put more then one file at CMDLINE (-f)
#               - added a new option, that the user can pass the address of
#               the command file, and it'll use wget to get it (-w)
#               - now -s does the grep at the selected command files (default,
#               -f or -w)
#
#               Jul 23 2007 - Modified - Ricardo Salveti de Araujo
#               - added flag to get the command file that has all failed tests
#
#               Sep 11 2007 - Modified - Subrata Modak
#               - added option to create Failed File if it is not an absolute path
#               - added option to create Output File if it is not an absolute path
#               - added option to create Failed File compulsory, even if user has not mentioned it
#
#               Sep 14 2007 - Modified - Ricardo Salveti de Araujo
#               - cleaning and removing duplicated code
#
#               Oct 27 2007 - Modified - Ricardo Salveti de Araujo and Subrata Modak
#               - better ways to integrate "ltp/tools/genload/stress" with "ltp/runltp"
#               Nov 24 2007 - Modified - Subrata Modak
#               - Added a new option to generate output in HTML format also. Also retaining
#                 the original test format
#               Nov 28 2007 - Modified - Subrata Modak
#               - Added a new option to mail back LTP reports
