#	CREATED BY:  Mark Emmerich
#
#	This program reads the file SPECIAL to determine what
#	to do about each of the programs contained therein.
#	SPECIAL is assumed to have the following format:
#
#	  PATH           S                     or
#	  PATH           C      CONVPROG
#
#	where PATH is the full path name, S indicates that the
#	file is to be "Saved" from the earlier version, C indicates
#	that the file is to be "Converted", and CONVPROG indicates
#	which program to use to perform the conversion.

All system files have now completed their conversions.  Your
system is effectively a 3.51 system.  There were however, files
on your system which were left over after the conversion.

A copy of these files has been saved in folders:

                  $SAVEDIR      or
                  $CONVDIR

			should you wish to examine them.


-END-

Your system files have been converted to 3.51.

A log of the conversion has been saved in /usr/adm/convert.log.

The following files have been replaced by newer versions.  The old
version of each has been renamed, starting with the original file
name and ending with '-old', should you wish to examine them.

     For example, the original file "/etc/shutdown" has been
     renamed to "/etc/shutdown-old".
