# Description:  Tidy up a Perl program - make sure the indentation is correct
#               The tidy parameters are set on a per directory basis in the
#              	perltidyrc file - if there is not one in the current directory
#               it looks in the home directory of the current user.
#               Update the perltidyrc file to change the main parts of perltidy.
#               The format is based on the Best Practices written by Damian
#               Conway - "Perl Best Practices"..
#
# Date          Change
# -----------------------------------------------------------------------------
# 05/09/2005    Auto generated file
# 05/09/2005    Needed to wrap the Perl Tidy utility with my own options
