Packagemaker 3.0.3. get user's installation preferences

Question

Hi all,
i have a small problem that seems to be caused by my lack of knowledge on the issue. Basically, what I am trying to do is to create an installer for my application with the PackageMaker.app. I am stuck on one place though, how can I 'get' a user's input during the installation and feed it to a script which is getting started after the install.
Example: I give the user 4 language choices during the installation - german, japanese, french and english. The user chooses one of those and according to this choice my post-install script has to do different things.
Does anybody know how can I achieve such behaivior?
Thanks in advance.

I am still struggling with the postinstall script... The problem is the PackageMaker does not give ANY language information to my script i tried many different things for example:
#!/bin/sh
/usr/bin/env
echo "arg0: '"$0"'"
echo "arg1: '"$1"'"
echo "arg2: '"$2"'"
echo "arg3: '"$3"'"
echo "arg4: '"$4"'"
echo "arg5: '"$5"'"
echo "arg6: '"$6"'"
echo "arg7: '"$7"'"
echo "arg8: '"$8"'"
echo "pkgpath: $PACKAGE_PATH"
echo "language: $LANG"
echo "messageLanguage: $LC_MESSAGE"
echo "environment: $ENV"
The output is:
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg0: '/private/tmp/scripts.eDmN/./postinstall'
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg1: '/Developer/Projects/TS-S2/code/trunk/Mac/TS-S2/Setup/BETA/MyApplication - Installer.pkg'
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg2: '/Applications'
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg3: '/'
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg4: 'upgrade'
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg5: ''
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg6: ''
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg7: ''
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: arg8: ''
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: pkgpath:
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: language:
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: messageLanguage:
...imac /private/tmp/scripts.eDmN/./postinstall[1503]: environment:
Where you can see that more then half of the variables are empty. Also the '/usr/bin/env' outputs nothing related to language or localization... I think, I set the localization properly in the packageMaker interface so the problem should be somewhere in the script. I am not experienced at all with writing scripts so I am guessing that is the problem. Any help will be appreciated. Thanks!
