# Version   Who      Date        Description
# 1.0       APY      09/06/99    Created
# 2.0       APY      31/07/01    WIN32 support
# 3.0       DDP      04/02/04    Microtec support
#                                Added a "-m libraian_path" switch to interwork
#                                with the MRI68K and MRICF toolsets
#                                Use -m \$(mri_librarian) to access the librarian
#                                to be used.
#           APY       20/05/04   -t and -a options
#                                1.2.0
#           DDP       23-Nov-04  1.3.0:
#                                Remove use of basename.
#                                Under Win32 $0 contains \\ and basename
#                                does not work.
#                                Added -n switch
#                                Prevent redirection to /dev/null for systems
#                                in which this doesn't work.
#           DDP     10-Jan-05   There is no windows/solaris way to determine the
#                               srcipt name - just name it.
