#  Part of automation of the testing process for the Tokenizer/De-Tokenizer
#  Automate Comparison of results of Auto-Execution of the various test-cases

#  Updated Fri, 16 Jun 2006 at 12:12 PDT by David L. Paktor

#  To Do:
#    Conditional comparison of .DeTok files:
#        Detect difference in .fc file, but do not display
#        Display differences in .Log file
#        If difference detected in .fc file, display mssg
#        Otherwise, detect difference in .DeTok file and display mssg
#        If either diff detected in .fc  or in .DeTok file, show .DeTok  diffs
#        Display differences in .RomHdr
#
#    Compare the source (.fth) files (for regression testing...)

#  Usage:
#  Run this from the parent-directory of the various Test categories.
#  This script uses the same  TestArgs  files that were used by
#     (and described in) the  AutoExec  script.
#
#  This script needs a shell environment variable called  CygTestLogs
#      whose value is the path to the parent-directory that contains
#      the results of Auto-Execution of the various test-cases under
#      Cygwin, which is the "Gold Standard" to which the other
#      platforms' results will be compared.
#
#  This script accepts an optional environment variable called  LogFilesDiff
#      which may be set to change the number of lines by which two .Log
#      files are expected to differ (due to different compilation-signatures)
#      If this is not supplied in the environment, a default will be provided. 
#
#  This script compares only one platform's results at a time;
#      the parent-directory that contains the Auto-Execution  results
#      for the platform to be compared should be the current directory.
#
#  This script displays both operational errors and detected discrepancies
#      in Standard Output and also collects the same in a log file whose
#      name is  AutoComp.Log.<time-and-date-stamp>
#
#  A secondary output file, called AutoComp.TKdiffs.<time-and-date-stamp>
#      is produced; it can be "source"d to cause a sequential  tkdiff  of
#      the detected discrepancies


#  Set the number of lines by which two .Log files are expected to differ.
#      (this is due to different compilation-signature lines)
set LogFilesDiffLines = 6
#  Over-ride with optional shell env't variable called  LogFilesDiff
