Hello,

I have finally succeeded in finishing my program (thanks to a couple of
people helping in these groups, too). It is packaged into a DMG all
right but I still have two questions.

First, I'd like to have a background image when the user opens the
package. It is described in quite a few places and, as far as I can
tell, I did follow the instructions, yet it fails to show up. I have a
background picture set up in the original folder, correctly showing up.
This will be copied to the DMG, including the .DS_Store file. The
picture will also be there, of course (invisible, in its own folder).
Yet, when I open the DMG, the icons will be in their proper customized
place (what seems to suggest that the .DS_Store *is* read by Finder)
but without the background image.

Second, I have to prepare my license agreement in Hungarian as well as
in English. The .r file containing the text resource refers to
languages using numbers like 50nn. I couldn't find and reference to the
code for Hungarian.

This is the script I use to create the disk image (as this operation
will be repeated often, I prefer to have it scripted rather than doing
it with the mouse every time):

=====
#!/bin/bash

if [ -z $1 ]; then
 echo "Error: specify serial number"
 exit 0
fi

echo "*** Creating Disk Image"
hdiutil create -ov -size 1m -fs HFS+ -volname "VOLUMENAME" temp.dmg
hdiutil attach temp.dmg

echo "*** Copying files"
/Developer/Tools/CpMac "path/Readme.rtf"
"/Volumes/VOLUMENAME/Readme.rtf"
/Developer/Tools/CpMac "path/.DS_Store" "/Volumes/VOLUMENAME/.DS_Store"
/Developer/Tools/CpMac -r "path/Product" "/Volumes/VOLUMENAME"
/Developer/Tools/CpMac -r "path/Background" "/Volumes/VOLUMENAME"
/Developer/Tools/SetFile -a V "/Volumes/VOLUMENAME/Background"
DEVICE=$(mount | grep "/Volumes/VOLUMENAME" | cut -f1 -d ' ')
hdiutil detach $DEVICE

echo "*** Resizing"
hdiutil resize -sectors min temp.dmg

echo "*** Compressing"
hdiutil convert temp.dmg -format UDZO -imagekey zlib-level=9 -o
"VOLUMENAME ($1).dmg"
rm temp.dmg

echo "*** Adding license agreement"
hdiutil unflatten "VOLUMENAME ($1).dmg"
/Developer/Tools/Rez /Developer/Headers/FlatCarbon/*.r "path/Licence.r"
-a -o "VOLUMENAME ($1).dmg"
hdiutil flatten "VOLUMENAME ($1).dmg"
=====
