# Abstract:
#   updtnum.pl will examine a specified file and update the build version
#   information located in it. the file will look something like
#      BUILDDATE=1999-11-12-2300
#   which means the current build is the build begun at 11pm on 11/12/1999.
#   the current file is set to %_NTBINDIR%\__blddate__
#


# simple test for usage
