   Your system is administrated under a NIS setup,  you may like to stop
   this installation at once and contact your network administrator first.
   
   It is recommended to have all files and directories owned by this
   Adaptive Server Enterprise installation under a single group named
   "sybase".  We also recommend you to setup an account for Database
   Administrator (DBA) operations under the owner "sybase".  The
   permissions and ownership of the files should be left as they are.

   This completes your Sybase Adaptive Server Enterprise (ASE) package
   installation.  To run Sybase ASE, you may like configuring your master
   and sybsystemprocs databases by continuing the installation procedure
   after logging in as sybase and executing $SYBASE/install/sybinit.

   This action is the default when you login for the first time.
   Re-running this configuration procedure can be initiated by removing
   the .readme and .sybinit files from the 'sybase' installation
   directory.

EOM
}

MsgAgree () {
cat <<EOM

   You did agree with the LICENSE conditions!  Please register your
   installation by visiting:
   
   	<http://linux.sybase.com>.

MsgDeny () {
cat <<EOM

   YOU DID NOT AGREE WITH THE LICENSE CONDITIONS !

   You may like to have a group for sybase installed.  Restart the
   installation script under your root account by executing:
   
   $SYBASE/install/sybinstall.sh

# This way, we decided (last minute) to have the LICENSE and
# configuration script execute from a different installation level.

# If your Sybase ASE release area is not /opt/sybase change the
