Configuring ntb-xdvi

EOF

cat << EOF

You have installed the package ntb-xdvi. The dvi driver xdvi displays
dvi files under X. You can configure the driver with a X app-defaults
file in /usr/lib/texmf/X/XDvi.

EOF
echo -n "Do you want to edit XDvi now (with $editor) [y/n]? "
read ANS
if test "$ANS" = "y" -o "$ANS" = "Y"; then
   cmd="$editor /usr/lib/texmf/X/XDvi"
   echo Running $cmd
   $cmd
fi

cat << EOF

You must crete a symbolic link for the XDvi file to your app-defaults
directory for X11. You can do this now or later with the command

ln -sf /usr/lib/texmf/X/XDvi <app-defaults-dir>/XDvi

If you do this now you need to know the path for your app-defaults
directory, for instance "/usr/openwin/lib/app-defaults" or
"/usr/X11/lib/X11/app-defaults". (Please also type the double quotes!)

EOF
echo -n "Do you want to create the symbolic link now [y/n]? "
read ANS
if test "$ANS" = "y" -o "$ANS" = "Y"; then
   echo -n "Your apps-default directory: "
   read APPDEFAULTS
   if test -d $APPDEFAULTS; then
      rm -f $APPDEFAULTS/XDvi
      ln -s /usr/lib/texmf/X/XDvi $APPDEFAULTS/XDvi
   else
      cat << EOF

I could not find this directory. Please check this and create the
symbolic link later with

ln -sf /usr/lib/texmf/X/XDvi <app-defaults-dir>/XDvi
