##########################
# ----------------------------------------------------------
# Sub: TIEHASH
#
# Args: {named parameter list}
# -argv A list of command-line options to parse as settings
# -preset A list of pre-set options to include in settings
# -version A message printed out for the --version command
# -<any> Any valid Config::IniFiles parameters
#
# Description: Contructs an object tied to the hash
# with a tie call. The -argv list is parsed for
# settings file names and overrides =~ -.*

# Date Modification Author

# 2000Mar21 Created the function JW
# 2000Jun14 Fixed include file processing JW
# 29Jul2002 Fixed -default issue with -import using existsJW
# 05Dec2002 Looks in script dir for config file last JW
# 27Feb2003 Added CGI mode parameter processing JW
# 09Mar2003 Added -preset because -arg is ignored in CGI JW
