.H 1 "Introduction to Software Notes"
.P
This book identifies and recommends some of the changes and
workarounds which have come about as a result of
the extensive enhancement and standardization of
UNIX System V Release 4.0. It is recommended as 
a preliminary source of information.
These notes address primarily source code related 
concerns. Information has been organized under
individual section headings in each chapter.
This introduction includes a read me first section
of operations notes which may be helpful to
administrators and programmers who are running pre-
SVR4.0 packages.
Additional software notes will be issued in the future. 
.H 2 "Read Me First"
Customers should be aware that some pre-SVR4.0
application packages may overwrite files and
disrupt symbolic links on SVR4.0 systems. 
.H 3 "CTC Utilities and POSIX tar"
The pre-SVR4.0 CTC utilities package overwrites the
existing POSIX tar. It is necessary to delete
\f4/etc/tar\f1 after the installation of the CTC
package and create a symbolic link, \f4/etc/tar\f1,
that points to \f4usr/sbin/tar\f1.
